That is not a logical way of looking at anything.
deities have a valid historical origin, one can follow many myths back to a deities origin.
the same cannot be said for ET in the same context.
imagination based on fear, wants and needs.
only in imagination land
not true at all.
we know OUR reality very well, the reality of living is not a mystery. If you imagine everything is hocus pokus then you will not live reality.
If you understand life is short, you are born you live and then die, it takes the mystery out.
You are talking philosophically, wondering more then anything leaving everything open to imagination.
Not a "logical" way of looking at things or not a historically valid way of looking at things? And don't think it isn't obvious to everyone else that you have a chip on your shoulder where religion is concerned. In any case, I don't see any logical problems at all. You can certainly say that mythological deities have a history, but I wasn't aware that having an earth history was necessary to be a deity. That mythological deities have to have earth history speaks to me about the nature of myth, not about the nature of deities. It is, however, for me a largely moot point since I don't advocate the worship of a deity or extra-terrestrial, nor do I consider any mythological being likely to exist. so I don't see why any of this would matter to you.
If you are going to purposefully misconstrue statements of cosmology for statements made about life on planet earth, then there can't even be meaningful discussion between us.
I frankly don't care if the universe (let alone earth or life one earth) was created. An ET of exceptional knowledge/capability (hell us in the future might well have done it even) could have done it, and it still wouldn't mean a single thing about whether or not reality as a whole was created.
Everything SHOULD be open to exploration of possibility, and it is only when evidence informs us that we should alter the probabilities in some way that we should restrict what we consider probable. Unless you have a spare reality lying around, then we really can and do know nothing about reality itself.
If your argument is that we should restrict debate about cosmology until we fix the problems with our life and living area, then I wouldn't disagree. But that is not the same thing as giving up on speculation nor is it the same as declaring speculation defunct. Paradigms are important; the ideas that you generate are enclosed by your world view (if your world view does not support an idea, then there is a very strong chance that you cannot come up with that idea).
As a side note: If you actually feel as though life has no mystery and that exploring the various possibilities for the universe (or whatever is beyond it) is pointless, then I pity you. There is beauty to be found everywhere: from the smallest particle to the largest celestial object and every thing in between. And what we know compared to what we don't know is a mere drop in an ocean of possibilities. We are ignorant, but if there weren't mysteries left, then we wouldn't have anything left to solve.
