Well...seriously, I'll ponder this one.
Could the sun have been the last cradle of life that exploded and that's why life is on earth?
I don't think so, if modern science is correct. I prefer the version where Mars had to evacuate, and we were a destination for refugees, and we're descendants. Or there could have been two or more completely different civilizations, one on earth and one on Mars.
I mean, on mars we have evidence of water (it's there), even liquid water(they compared photographs of an area at different times and found liquid erosion). We have the pyramids on Mars, the face, the sphinx, and all the weirdly precise mathematical ratios (check it out somewhere) between the objects.
Here on Earth we have the huge paintings in a desert somewhere; the Stonehenge, possibility of an Atlantis, of Noah's Ark, of bigfoot (large underground fire-eating apes that show up when they want to).
And let's not forget all the conspiracies and possible theories. There's always the chance that we're all puppets and the governments are withholding technologies from us "for our own good", or maybe there are Men in Black like in the movie. That's what I'm sometimes thinkning about.
