Buddy is just parroting the main stream narrative, which I dont know, again some virus's are so big they can be seen with a typical microscope.

You guys believe in dna, but not virus's, but what the hell is a virus, but a rogue piece of rna/dna. Head scratcher for sure.

Couple thoughts though.

1. This is the thing about dna, I remember hearing someone give a lecture once about how if you wanted to send a message through space and time, dna would be your best bet. Why? Well I talked about this before, but by using 4 bits, its basically a super code, and has built in redundancy's.

The main source of genetic redundancy is the process of gene duplication which generates multiplicity in gene copy number. A second and less frequent source of genetic redundancy are convergent evolutionary processes leading to genes that are close in function but unrelated in sequence (Galperin, Walker & Koonin 1998).

But there’s another potential way to send signals across the cosmos, albeit one that requires a great deal of patience and expertise: storing messages inside genetic material. Encoding a message in an organism or virus and then sending it on an interstellar voyage to other planets requires a long wait—it might take eons for intelligent life to evolve on the destination planet, where the message is waiting—but these organisms, packed with a message, are patient, and they are fecund. They quietly reproduce, carrying and copying the message hidden within their informational backbones. Until one day a sentient being takes notice of the momentous message all around it (or even within itself): “You are not alone.”

If this sounds like something out of science fiction, that’s because it is. When I was in elementary and middle school, I loved Star Trek: the Next Generation. I grew up on it. And in one of the later seasons, an episode aired that examined this idea.

This particular episode’s plot revolves around a chase to collect pieces of genetic material, ones that turn out to exist within many of the intelligent species commonly found in Star Trek. Humans, Klingons, Romulans, and more, all turn out to be related to a common ancestor, who placed information about our origins—that our planets were all seeded with biological information by this progenitor—within our own ancestral genomes. A fun idea, which sent the characters on an Indiana Jones-style romp in search of biological samples necessary to put together the genetic puzzle.

Under one system, a single gram of DNA could store 215 million gigabytes of data, and a quantity of DNA smaller than a sugar cube could store all the movies ever made. A container of DNA about the size of two passenger vans could hold all the data ever created in the world.

One reason for all this density is DNA’s four-part base — A, T, G and C — as opposed to the binary 0-and-1-based system that computing uses now, Sandhu says. This doubling allows for “exponential growth” in the amount of information stored. NAM storage encodes information in molecules, packing informational punch in very tiny parcels.

And 2.

All external factors leave a mark on are dna. From the food we eat, to the stress we have. Not just virus's, but they do happen to contribute genetic material which may or may not be used at some point in the line. But considering all life on this planet is so similar cellular wise, thats not to shocking to me.

Environmental epigenetics describes how environmental factors affect cellular epigenetics and, hence, human health. Epigenetic marks alter the spatial conformation of chromatin to regulate gene expression. Environmental factors with epigenetic effects include behaviors, nutrition, and chemicals and industrial pollutants. Epigenetic mechanisms are also implicated during development in utero and at the cellular level, so environmental exposures may harm the fetus by impairing the epigenome of the developing organism to modify disease risk later in life.

The next time you wolf down that Big Mac with large fries consider you may be affecting more than your own waistline. Scientists now say an unhealthy diet can be encoded into DNA, which is passed down to future generations.

By now, most people have heard various negative things about a Western diet: it is too fatty, too salty and too sugary. It can cause problems to the immune system, disturb the chemical makeup of the stomach, and, perhaps the most obvious of all symptoms, lead to obesity.

Now, a study from the National Institute of Allergy and Infectious Diseases in Maryland has provided yet another reason to drive past your favorite drive thru window: the deleterious effects of a poor diet can leave a mark on the DNA, passing along the genes to your offspring.

Your not wrong, but its amazing that you guys cant imagine a entirely different universe at that scale so much to the point you think virus's are not possible, but to each their own.

If anything is alien though, its proably fungi, its essentially what kick started life on this planet, seems like it would be a pretty important tool in transforming a lump of rock into something like this.
