Then we wouldnt be here.... Where does that logic come from? My jaw dropped at the sheer idiocy of that comment, cause it makes no sense. Yeah, call a fool a fool. You're a fool. If the sun was alot hotter and mars was like earth what happened with the life on there? You do know with an environment like ours shyt just magically grows, stop smoking that f.ucking pot and maybe you'd be getting this, anywayz say whats his face is right and the earth could sustain the same amount of life or whatever with warmer weather, and if so what time line are we talking about, the dinosaurs or the "ice age" cuz if it was around the ice age then would it still have been as cold, cuz if not then wouldnt this change the evolution of some animals, and if this was back in the dino era then was this when the earth was "mostly water" and is that was caused the evaporation and the creation of our plante's climate? So lets say mars was earth and earth was either A. Still a ball of burning gas/rock B. A giant ball of water or C. A nice torpical paradise and lets also say that the sun's power somewhat dimmed it's light bulb and got less hot, then whatever kinda water/life on mars be some what preserved or have some kind of trace? Or is all of that burried underneath all of the planets debris from it's violent storms or did the sun have some kind of power surge and like toast mars but yet some how leave earth out of harms way. I love your theories they were very insightful.
