Carbon has 6 electron, 6 protons, and 6 neutrons - Grephene is a derivative of Carbon, meaning it is made out of the same componenets... This should help you understand -> https://conspiracies.win/p/17rmA2byCb/666-in-carbon-graphene-and-mrna-/c/

I understood that but as I said everything is made of carbon so why is graphene oxide in particular the mark?

Where are you getting this from?

The Beast from the Earth

11 Then I saw another beast coming up out of the earth, and he had two horns like a lamb and spoke like a dragon. 12 And he exercises all the authority of the first beast in his presence, and causes the earth and those who dwell in it to worship the first beast, whose deadly wound was healed. 13 He performs great signs, so that he even makes fire come down from heaven on the earth in the sight of men. 14 And he deceives [f]those who dwell on the earth by those signs which he was granted to do in the sight of the beast, telling those who dwell on the earth to make an image to the beast who was wounded by the sword and lived. 15 He was granted power to give breath to the image of the beast, that the image of the beast should both speak and cause as many as would not worship the image of the beast to be killed. 16 He causes all, both small and great, rich and poor, free and slave, to receive a mark on their right hand or on their foreheads, 17 and that no one may buy or sell except one who has [g]the mark or the name of the beast, or the number of his name.

18 Here is wisdom. Let him who has understanding calculate the number of the beast, for it is the number of a man: His number is 666.

Rev. 13

That's the narrative of the end times. You can't just cherry pick the mark of the beast ignoring the rest (including the chapters before it).

Here's a prophecy by orthodox st. Paisios of Athos talking about our times:

Two thousand years ago it was written in the Book of Revelations that people will be marked with the number “666.” As Holy Scripture says, the ancient Hebrews laid a tax on the peoples they conquered in various wars. The yearly tax was equal to 666 talents of gold. (1 Kgs 10:14: the weight of gold that came to Solomon in one year was six hundred threescore and six talents of gold-, and 2 Chr 9:13: the weight of gold that came to Solomon in one year was six hundred and threescore and six talents of gold). Today, in order to subjugate the whole world they’ll once again introduce the old tax number linked to their glorious past. That is, “666” is the number of mammon.

Everything is going as planned. They put the number a long time ago on credit cards. As a result, he who is not marked with the number “666” will be unable to buy, sell, get a loan,or find work. Providence tells me that the Antichrist wants to subjugate the world using this system. It will be foisted upon people with the help of the mechanisms which control the world economy, for only those who receive the mark, an image with the number “666,” will be able to take part in economic life.

The mark will be an image which will first be placed on all products, and then people will be compelled to wear it on their hand or forehead. Little by little, after the introduction of ID cards with the three sixes, after the creation of a personal dossier, they’ll use cunning to introduce the mark. In Brussels a whole palace with three sixes has been built to house a central computer. This computer can keep track of billions of people. And we Orthodox are resisting this because we don’t want the Antichrist and we don’t want dictatorship either.

The most we can suffer is martyrdom.

There will be three and a half hard years. Those who don’t agree with the system will have a rough time. They’ll constantly be trying to imprison them, using any pretext they can find. They won’t torture anyone, but without the mark it will simply be impossible for a person to live. “You’re suffering without the mark,” they’ll say. “And if you had just accepted it you would have had no difficulties.”

For this reason, by learning to live a simple, moderate life here and now you’ll be able to get through those years. By getting a little bit of land, raising a little wheat and some potatoes, planting some olive trees, and keeping animals of some sort, a goat or chickens, the Christian will be able to feed his family. Stockpiling is of little use: Food doesn’t keep for long before spoiling. But these oppressions will not last for long: three, three and a half years.

For the sake of the chosen the days will be hastened. God won’t leave a person without help. Tomorrow thunder will strike, and the brief dictatorship of the Antichrist-satan will come. Then Christ will intervene, will give the whole anti-Christian system a good shaking up. He’ll trample upon evil and turn everything to good use in the end.

•   And if someone receives the mark unknowingly?
  

It’d be better to say “uncaringly.” How can one be unknowing, when everything is crystal clear? And if a person doesn’t know, then he should become interested and find out. By accepting the mark, even unknowingly, a person loses Divine Grace and gives himself up to demonic influence. When a priest immerses the infant in the baptismal font, the infant receives the Holy Spirit without knowing it, and Divine Grace begins to abide in him.

•   Some people say: “What’s destined by God to be will be. What business is it of ours:
  

They can say whatever they want, but in reality it’s not like that! Unfortunately, some modern priests diaper their flock like infants, to keep them from getting upset. “What’s going on today isn’t important,” they say. “Don’t be alarmed. All you need is to have faith in your hearts.” Or they scold: “Don’t speak on that topic, about ID cards or the mark of the beast. It will just upset people.” If they were to say instead: “Let’s try to live more spiritually, to be nearer to Christ and not to be afraid of anything. You see, the most we can suffer is martyrdom,” then they’d at least be preparing their flock for the com¬ing tribulations. Knowing the truth, a person will begin to mull things over and shake himself out of his sleep. What’s going on will begin to cause him pain. He’ll begin to pray and to be on his guard, so as to not fall into that trap. What do we see now? It’s bad enough that cunning “interpreters of Scripture” are commenting prophecy after their own fashion. They’re representatives of the clergy, but they’re more cowardly than lay people.

And it would behoove them to exhibit a healthy spiritual unease and help Christians by sowing beneficial concern so they’ll be strengthened in their faith and receive divine consolation. I’m amazed: Doesn’t what’s happening give them any cause for concern? And why don’t they at least add a question mark to the interpretations they come up with? And if they help the Antichrist and thus lead other souls to perdition?

No, behind the “perfected credit card system,” behind “computerized security," lurks worldwide dictatorship and the yoke of the Antichrist: And he causeth all, both small and great, rich and poor, free and bond, to receive a mark in their right hand or in theirforeheads. And that no man might buy or sell, save he that had the mark, or the name of the beast, or the number of his name. Here is wisdom. Let him that hath understanding count the number of the beast: for it is the number of a man; and his number is six hundred threescore and six. (Rev 13:16-18).
