These are two really good points.
I would like to think that if there had been another species-and given your parameters for behaviour-that we would have evolved to a higher level of consciousness, maybe the collective subconscious would be an open resource for us all for example. This would mean we could communicate from here in Britland to Oz without the need to type cos you would be reading my thoughts.
Regarding same time same place different experiences, I went home to a friend's father's funeral a few months back and it seemed like time had stood still. Most of my early life friends were still there and had been doing the same job for years. I have had to travel up and down the country with my various jobs and left home when I went to my first Uni , since then I have been an itinerant. Part of me wonders what would have happened if I had stayed.
Its a bit like the old buddhist story:
A buddhist monk was sitting by the side of the road midway between two towns. A man approached him coming from the first town and on his way to the second.
He asked the monk " I've just left this town, the people were so friendly and we had parties and get togethers and life was great, what is the second town like ?", the buddhist replied " much the same ".
A little later another man approached the buddhist, he too was heading for the second town, he asked the monk " I've just left this town, the peple were so unfriendly and unhelpful, what is the second town like ? ", the buddhist replied, " much the same . "
