It's Highly Probable That We Have Lived on Mars

  Probably not highly probable, but upvoted because I love stuff like this. We really don't know very much about the distant past or the "big questions," so radical stuff is always within the realm of possibility at the very least.

    It's near-to-impossible to quantify this, but again, "there's enough uncertainty to open up our minds". Thank you very much for your comment by the way, writing though-provoking stuff and seeing smart people discuss those ideas is truyl fulfilling.

      There's far too little bold speculation and question-asking these days. It wasn't always this way. When I go back and read eminent scientists from the 50s and 60s I am pleasantly shocked by their fearlessness. You can go further back too. Thomas Edison built a machine to experiment with electromagnetic communication with the dead. Silly? Perhaps. But I see that as evidence of a questioning and a questing mind that wasn't afraid to ask big crazy questions. No professional would dare anything like that today unless they were so independently wealthy they didn't need anyone else's support. We've turned into a bunch of careerist cowards who keep our heads down out of the conditioned fear that expressing anything "far out" might offend some bureaucracy or ideological group. The irony is that the 50s and 60s were far more buttoned-up when it came to cultural norms, dress codes, etc. We've liberalized in one way but gone hyper-conservative in another.

  It's much easier. Just dig in the Earth and find the launching pads, or the metallic tools used to create the ships, or ... Bronce was discovered in ~3000BC and cooper in ~4500BC. They left nice objects that are easy to find by archeologist. Before that, it was impossible to build a starship.
