Was life on Venus long ago? Is Earth the stepping stone to Mars?

A long time ago, maybe, millions of years ago, Venus might have had an atmosphere more suited to life as we know it here on Earth today, then maybe the idea of us having originated from there, to here where we exist today. We might be turning our planet into a second Venus? Well, in that case, we might need to move beyond our planet and seek out Mars to become the third place for us humans to adapt? The theory of humans or beings like ourselves, having originated from elsewhere in the universe and planting the seeds of life on other worlds, might suggest this possibility. In a universe full of billions of galaxies, that contain billions of stars which are likely to have planets circling around them, it is not so far fetched that, over the millions of years and the universe is around 14 billions of years old. If man today came from another world, it might have been from planet Venus. Maybe Venus is messed up now but maybe it wasn't always. If man is able now to go to the moon and maybe even Mars. Then think about the possibility of life forms that are able to space travel, they might leave a planet that has become uninhabitable and moved to Earth as their second home or maybe our origin goes back even farther. Maybe humans once lived in another galaxy even. So, in theory, the Earth is a planet that we are messing up so badly that in a few hundred or thousand years from now, we might have made it to Mars and even managed to terraform that planet by whatever method that would exist by that time. Hopping along the universe from planet to planet, galaxy to galaxy, who knows? If we find a way to move some humans to Mars just to keep the human chain of life going, using a space ship like Noah did with his arc, animals, plants and bacteria as well might find a new place to grow.
