Okay, you know I agree with you that people were people...even 60,000 years ago. Until shown otherwise I am going to assume that HE evolved into people a long time back. And they had boats.
But there are differences between today and 60,000 BC as far as we know.
First, a Haitian standing on the shore gazing towards Florida KNOWS that Florida is there. He probably has relatives living there. For that matter, a Goth heading west in the 5th century knew that the Roman Empire was ahead of him....and the Huns were behind him. There was trade and diplomatic missions, etc. So the element of venturing into the unknown was not present. We really can't say the same for the guy standing on the south coast of Australia and gazing in the direction of Tasmania. We have no way of knowing what he knew or thought.
Second, there is a difference between climbing a hill to look into the next valley and setting off on a boat onto the open ocean. One can be reasonably certain that there is land on the other side of the hill but can one say the same about a sea voyage? True, a scouting party could be sent but that just means that someone has to go, look around, sail back, convince everyone that things are better in the new place and then everyone has to sail there. Possible? Of course. Likely? I don't know. I wouldn't want to have to figure out the probabilities on that one.
Third, yes I agree that some individuals are adventurous in general groups are not. Daniel Boone went to explore Kentucky. Mrs. Boone stayed home with the kiddies. If I were a leader of a group I would need a hell of a reason to move my entire group (women, children, elders) into the unknown. Those reasons might include famine, drought, the appearance of an enemy, a volcano blowing up, something which threatened the survival of the group. I'm just not persuaded that people would voluntarily move from a place which was meeting their needs without some sort of stimulus.
Fourth, these HG groups are generally considered to have been quite small. Even if someone wanted to go exploring could the group have afforded to let one or two prime hunters take a little trip? If you subtract out the young, the old and the women how many hunters of prime age could there be in a group of maybe 30 people? Five? Six? I don't know. It seems that survival would be dependent on keeping the most productive members of the group around.
Anyway, the dog protested that I seemed distracted on our walk.
Something is wrong here. War, disease, death, destruction, hunger, filth, poverty, torture, crime, corruption, and the Ice Capades. Something is definitely wrong. This is not good work. If this is the best God can do, I am not impressed.
