Our scientists understand that modern humans date back about 200,000 years, with behavioral modernity coming in to play about 50,000 years ago. So many branches leading back to a very simple source.
I ask you to contemplate the patterns of your family, your parents, your grand parents. I invite you to ask how many patterns you are unconsciously repeating. How many of those patterns may very well link back to that initial evolution of modern humans. Of those patterns that do not serve you, your fellow humans, your planet well, how many have you defeated? Re-imagined? How many patterns will your children shoulder because you couldn't/didn't see? How many will they break? How many will make it to your grandchildren?
I ask you to consider that you don't have to believe everything you think.
