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

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.

Thank you for posting this, navane. I would like to watch that documentary.

Dumb question, but my curiosity told me to ask.

lol
I highly doubt aliens and Neanderthals had sex and reproduced. 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.
