So much for astronomy since Hubble.
What? How does observing distant stars "prove" that a man evolved from a duck three hundred billion years ago?
Hey, if science had a "time scope" where they could look back in time to the beginning of life as it actually happened, similar to seeing light that was emanated billions of years ago, then that could be called rigourously testing a theory.
But they don't and so sherlock holmes it is.
