That's not even remotely true, stop watching anime.

Those are the cyclical needs which we base life outside of earth on. Take away the sun and there is no hope of life. Its the reasons humans all over the world worshipped the sun wayyyyyyy before the bible (or judaism for that matter) came out.

Humans didn't evolve from chimps, yet we do have a common ancestor and share 99% of dna with chimps.
We even share 70% of DNA with this

But sure the seeds of life could have come from another planet. Perhaps we're all evolved from Martian bacteria, or from proto dna from a different solar system. Yet humans are very much part of Earths tree of life.

This can't be serious. We have the entire human DNA mapped out and there is no source of any alien life in the planet from any living thing we have ever tested.

You lack basic understand of biology, ecology and genetic to come with a theory like this.

All life here either has RNA or DNA, which an alien life wouldn't nescessary have it also.

I think early humonz might have sexed with some advanced alien species and they evolved intelligent whereas other animals did not. Every now and then they come looking how far we've progressed. Ufo's have been seen since ancient times. or we all live in a simulation

Well, there you go. Everyone is part of the same universe, so no one can really be an alien.

It's simple, Earth was a discovered planet that had all the rights components to support life. But there was one problem, life on Earth was threatening. Dinosaurs were rampant, atmosphere was too dense and it would be impossible for intelligent beings to live on the surface of the planet.

Because destroying all life on a planet was prohibited, they still decided to land and try to live below the surface. Many died of starvation, low oxygen, disease, eaten alive by dinosaurs so they went back in space and came up with a plan. Take the DNA of many of the animals of their birth planet and hide it a huge meteorite. Then have that huge ass meteorite crash on Earth. This would wipe all life on the planet in an instant. Because a huge cloud would prevent the sun from bringing back life on the planet for some time, the DNA and seeds from the meteorite would flourish and bring new species on the planet. This would also prevent any native life from Earth to ever live again and make sure the new kings, the Mammals reign supreme on Earth.

They were found guilty though and were prevented from ever landing on the planet. Earth was banned from any touristic and business destination until it regains it's previous state. Things though didn't go as planned, humans appeared and they didn't look like them, but they are no threat, they think Earth is flat and don't go to space... oh wait!!!

this

More modern estimates point it to being between 89% and 96%. Some people are rather attached to it because... I don't know? Maybe it's an american thing, a sort of defense to keep those creationists from weaponizing a lower similarity on their favour? Mmm.

The 99% original estimate was funny because if you thoroughly analysed the DNA of a man and a woman, the difference would be more than 1% because the Y chromosome is over 1% of male genes has very little to do with the X chromosome, since they are millions of years apart of each other. The notion of males and females being further apart amongst themselves than a species removed over 5 million years is, of course, absurd. Only once I've seen a geneticist called on it on live TV eons ago.

OT - you might find interesting, if anything, to read Zecharia Sitchin, OP. His books even come on a boxed set which look like a completed fantasy series (hah) or something.

Well apart from the obvious 1 chromosone difference, it seems humans only differ 0.1% from each other.

I guess it depends on how you measure it? Chimp DNA already differs 1.2% amongs the species according to that source.

Creationist already did jump on that btw, that's what turns up when I look for < 98% claims

Yet 85% or 99%, still not alien, still share the same basic DNA structure.
