Good morning, Flobadob. I can't answer your question from a religious viewpoint, but I do believe there is a plethora of life elsewhere in the universe, and although that life may have evolved into forms unimaginable to us, I would assume that the basic building blocks remain constant throughout.
Why not? At the moment we know nothing else. However, that's not to say there is nothing else. Elsewhere in the Universe nature may in due course present, as yet, unknown quantities (and qualities). Who knows?
I don't want to spoil Flobadob's thread by taking it off course. He is looking for religious viewpoints.
I have no doubt about life being on other planets in the universe because Holly Quran speaks about that. As far as building blocks are concerned it is written again in the Quran that every living thing is made out of water or in other words water is one of the essential components. So some sort of similarities must be there.
If by God we mean the spirit of the universe rather than merely the spirit of man, then there should be room for belief in extraterrestrial life in religious or spiritual thought. Life in the universe, not just life on Earth, is all part of the plan from this point of view.
