A very interesting point of view although I've got to admit that he lost me somewhat along the way,he says that there are billions of billions of planets out there and so let's say that of ten billion planets only 0.01% can achieve any form of life that's still an astonishing 1,000,000 planets,out of a million planets has only one avoided the filter?
My only concern is that we are the first of the planets to achieve life, millions of years from now there will be more but we will so advanced that we will destroy whatever follows us,we can help ourselves, we've waged war among ourselves since the day dot so we are bound to nip anything in the bud that might threaten us,at the very least new species will be put into glass jars to observe rather than evolve naturally
