Other Worlds

Hello - I just wanted to contribute to the discussion on the forum. When I was checking my weather app today, I saw an interesting article about scientists confirming that Mars had weather systems in ancient times. What do you guys think about that? I feel like there was a time when Earth and Mars both were flourishing. I like to imagine that there was some contact from Mars to Earth, and a lot of the big structures that we know today were inherited by us humans (Pyramids, for example), were built by the same people who lived on Mars before it was destroyed. What do you guys think?
