There are billions of galaxies out there, billions of stars in each of them. There are trillions or quadrillions of planets in our universe and some of them harvest life. What happens in the bottom of our own oceans surprises us, let alone far planets around other stars in other galaxies (and assume that’s the only recipe for life).
Other life forms are extremely far and unreal, as if they don’t exist. But they most likely do, and so many of them indeed. But how do they look like? I think although our universe is ruling them all similarly, the potential is so huge that anything we can imagine proably exists somewhere. And anything that our imaginary creatures can imagine, could as well.
What other life forms may look like has not really captured our imaginations. Alien Planet – Darwin IV is the best (realistic, still very earthly) animation I have come across. There are many documantaries out there but no fictional motion pictures that I know of. If you know of some pleases hint me. If you haven’t watched this, give it a try. Don’t think fiction but more science. Think reproduction, growth, survival, energy, memory, intelligence. Think life! It’s fun.
