it suggests that a that is earthlike should also produce life. but doesnt it overlook the fact that all life on earth was spawned by a singular event. by its reasoning shouldnt life have also happened the day before and the day after since earth was earthlike on those ocations also. it should also have happened a few inches to the left and right in the primordial ooze as well. it seems to me that life on other planets is very unlikely since conditions on earth were probubly the same in very many places and for a very long time and it virtually never happened. even the most ideal lab conditions are unable to prompt the event. who has it wrong, me or drake, and why?
