what is fascinating is how old the universe is going to be, and how extremely early we apparently are. almost unfathomably early. Concerning future intelligent beings, maybe 100 billion years from now,  30 trillion years from now, maybe 90 trillion years now, evidence may be as overwhelming and as difficult to discover as it is to look at the moon. Us being so early is probably a good sign about other life in the universe. if we came about so early, it might not be too difficult when we look at time on the level of the universe.
