you do know why panspermia has become such a popular notion in the scientific community, right?
because the more we learn about molecular biology, the more life arising ex-nihlio on earth seems ridiculously impossible. the solution many favor over a creator god is that magical conditions necessary for life and/or its basic building blocks to begin out of dust existed on some other imaginary planet.
the argument goes like this:
"in order for X to happen there must be a purple cow"
"there is no purple cow"
"well the universe is pretty big. let's just say there was a planet somewhere in it full of purple cows, that blew up, and a purple cow on a bit of debris survived for millions of years in the cold, dead, irradiated vastness of space, crash landed on earth and started a race of purple cows here."
this is what's known as a "dull, rusty razor" belonging to a certain occam.
one might as well assume a hyper-intelligent species of white mice created the earth and all her life forms as an enormous supercomputer in order to calculate the meaning of life, the universe and everything. because the universe is so big.
