Colonizing Mars: Should Humanity Prioritize Colonizing Mars or Fixing Earth?

Oh, and to Zach, yes, I have read the book “Sapiens”.

Interbreeding did happen. But genetic facts show that the majority of modern human DNA traces back to African populations. I’ve also read from scholarly sources that non-African populations have small percentages (about 2%) of Neanderthal DNA. This is the interbreeding evidence between Homo sapiens and Neanderthals in Europe and Western Asia. If you look at Asian populations, they carry Denisovan DNA. It’s about 5% in some parts. That was the other group whose name I forgot. That’s evidence right there that there was interbreeding with them too.

Last night I was catching up on some items I had saved in my DVR, but I had not watched yet. One was an episode of PBS Independent Lens called Space: The Longest Goodbye. It is about how NASA has attempted to research how we humans might approach a trip to Mars as the journey is long and people who volunteer to go will experience extreme isolation.

The program was a little dry at first, but became more interesting towards the second half. When it comes to space exploration, people are focused on things like "science", technology and biology.....but are humans prepared to mentally survive? NASA hired psychologists to look into just that.

Y’all ever see those documentaries about how the Egyptians, Mayans, and Aztecs had pyramid art showing aliens? I’ve seen documentaries where the artwork shows aliens interbreeding with humans/non-modern humans — Neanderthals like Zach said. Y’all think that could have happened, if there are aliens out there? Dumb question, but my curiosity told me to ask.

What sources were you using, Zach? I’m asking because this isn’t true.

If there are/were aliens visiting Earth, for interbreeding to happen, the alien life forms would need to have DNA or a compatible genetic structure very similar to humans. IMHO, this is like a big “no way”, given the differences likely to exist between life forms that evolved on entirely separate planets. And there’s like no verified scientific evidence or fossil record to suggest that humans have DNA from non-Earth species.

Some ancient cultures like the ones you’ve mentioned have myths involving “gods” or aliens coming to Earth to mate with humans. I think these stories are more symbolic than anything, in order to explain natural phenomena, not actual historic events.

How do you know, CG? What makes you so sure this is impossible and never happened?

Aww shit Lmao!

If aliens are coming to earth in 2024… going to put that UFO in reverse and get the heck away from this dumpster fire

I don’t remember the source, but it’s funny that this article popped up on my phone this morning. It proves my point.
