Humans are the newest model of Life on Earth. We were meant to be extremely pure and innocent in nature but were mislead by 3 main groups:
Archons: Fallen angels of the Bible. They fell around 200,000 BC and took about 40 planets with them with Earth being one. These are just a bunch of disturbed souls who went insane when they meddled with evil practices. Deliberate, daily practice of evil causes insanity.
Reptilians: Although many species exist on many planets, the ones on Earth evolved from the Raptor Dinosaur. The Dinosaurs went extinct because they were gigantic with tiny brains so when they ate up all the food, they didn't know how to replenish it. The Raptor was a bit smaller and some survived. The Reptilians eventually joined the Archons in the "Lucifer Rebellion" but there is a group of them that have decided to follow the path of good. I suspect David Icke is one of the ones that chose good.
Greys: Greys and Reptilians used to have a lot of wars in the past. That is why the moon has all those craters in it. After many wars, the Greys became dominated by the Reptilians and enslaved by them.
The Archons are so far away from the mind of God that they cannot absorb God's energy and therefore lack energy. As an alternative, they take the energy of those suffering or dying which is why they turned this planet into an actual hell to create as much suffering as possible. They also can feed when People die which is why they promote wars and sacrifices. In exchange, they help Reptilians become rich and powerful. Many of the major CEOs, Royals, ect.. are all Reptilians. Greys are used as the foot soldiers for the Reptilians.
There were some other groups that have either left the planet or are very disconnected from humanity such as the Mer (fish People), Spider People who left or the Bird People. I suspect the Egyptian symbol of wings refers to the Bird People who might live on Nibiru now.
The Sasquatch evolved before humanity. They are extremely good and holy Spiritual People who believe in Jesus but were hunted down by the Deep State for knowing too much. There were genocides run on them. They even manipulated humanity against them even though they literally are our big brothers. The Sasquatch is currently the best group native to Earth. The fires they keep making in the woods are meant to kill them off because Sasquatch, like Reptilians, have many amazing psychic powers including the ability to detect People within a 3 mile radius. They can even shapeshift like Reptilians and often change into animals like Panthers. Sasquatch believe in humanity and seek to rekindle our partnership. (see book: Sasquatch Message To Humanity for more info).
I have read that Pladeans and Arcturians, along with others are also extremely holy and evolved beings that also believe in Jesus.
The goal of all universal Life is to grow the Soul to reconnect it with the body because all morals and energy comes from the Soul which is directly connected to God. The negative ET groups are just rebels of the game who decided to try to gain their power without earning it. They believe in selfishness and enslavement of others but their philosophy is flawed because this requires violated other People's Rights which leads to rebellions and trouble in the long run. Also, as mentioned, the practice of evil leads to insanity which means they suffer with paranoia, guilt and confusion on a regular basis. They lose their minds and become psychopaths totally disconnected from their Soul.
There is 1 rule that a lot of the negative ETs are fully aware of and that is not to violate anyone's free will. Andrew Tate explained how they get around this to some extent. He used this example: If the negative ETs sell you poisoned apples and put a sign up that says "poisoned apples" and you buy them and eat them, then you are committing suicide as you bought those apples knowing they are poisoned. This doesn't eliminate bad karma but it does reduce it. They also don't give any direct orders at the top. They train their employees to guess what they want. This way they reduce, but not eliminate, bad karma. Karma is an actual Law of the universe that cannot be changed. There are a few basic Laws that are always in play. Karma simply means anything we do to others will eventually be done to us not as punishment/reward but as a teaching tool so we see that negative actions are fruitless and positive actions are fruitful.
This is the gist of it. Also, there are positive ETs that want to help us but they cannot because, in higher wisdom, it is much better than Humans help ourselves break free. When we do help ourselves, they can assist because that wouldn't be violating free will. We can also mentally call upon them to assist because they can receive those kinds of messages. The invitation also prevents any free will violations.
There may be negative ETs that are at war with each other as well. This is because they know the end is nigh and have turned on each other. The Greys and Reptilians might be at war with each other again but I am not certain just yet. They are all just scrambling because eventually it is inevitable that the dark collapses and the good rises.
Lastly, a lot of ET are much older than Humans. We are considered age 4 going to age 5. There are ETs out there age 9, 11, 12, ect... who are rascals and will try to lie to you about the nature of reality to fulfill their own agendas. Some of these agendas are totally innocent in a way but still, be careful not to believe anyone blindly. Always weigh what People say on your heart which is a truth meter if you know how to use it.
I was interested until you got to the Sasquatch.
