Atheist are attracted to speculative science like pedophiles are attracted to the Roman Catholic priesthood. They both enter with seemingly pure intentions but, have their own motives for being there.
How does Zolensky know this meteor's age? He doesn't. He just picked an age out of thin air that suited his purposes. He doesn't even know where this rock came from:
"
They've survived somehow, intact on an asteroid for over four and a half billion years and where they come from, we don't know. But it's not from around here. It's from somewhere else."
Notice his keen powers of scientific observation at the end of the statement:
"It's from somewhere else."
So what pray tell is "organic globules"? Well first of all it's not organic; it's a rock. Secondly, the globules he's talking about are just pockets within the rock that hypothetically could have held that organic matter the Zolensky imagines could have existed 4.5 billion years ago. An example of atheistic science at its finest.
"Perhaps these are like little condos arriving on earth and biology can move in later on," said Zolensky.
You just keep believing that Zolensky. Believe real hard and maybe it will come true.
