If we were indeed "manufactured" by a superior species, and that the "experiment" was abandoned, then it could very well explained our obsession about finding out where we come from and who is our "father" ? a bit like an abandoned child looking for his mother, or attention from an adult
we are only the only animal looking up the sky ? why is that ? not even our close cousins, the monkeys, do that, and they are quite smart and organized in society with code and rules, and yet they don't worship anyone
Are we the only animals to believe in something like that ? shouldn't we be the gods ?
