What is the most probable: LIFE on Earth created/managed/decided 1. By God 2. Extra-terrestrial societies 3. Evolution (Universe)?

Option 1 - Every single thing in human history that was at one point thought to be divine in nature, has been eventually discovered to have natural causes.

Option 2 - Since we exist, it's possible (and indeed some would argue probable) that life exists on other planets. The fact that its a possibility that they exist, since we exist, gives this concept more weight than "creator" but there is still no evidence for it.

Option 3 - I assume you mean to say that we began our existence through natural causes, since evolution doesn't create life. This ultimately is the most probable. The reason for this being the most probable is that everything we have so far discovered has had a natural cause. Also, if option 2 is correct, then that society would have had a natural cause at some point. So why not cut them out of the equation unless compelling evidence comes to light. Occam's razor says that the theory with the least "ifs" is likely to be true. Therefore 1 and 2 are the least likely, and option 3 is the most likely. Even without evidence, that statement is true.

We are pretty confident that evolution is functioning, so #3 is pretty likely.

We haven't had any contact or solid evidence of extra-terrestrial societies, so that one's pretty unlikely based on what we know.

And unfortunately, God is outside of the realm of science; we really don't have a way to verify whether He did or did not do any certain thing. So with nothing to go on, the only honest thing to do would be to assign the probability at 50%.

Evolution does not create life. Evolution is the change in organisms over time, and for organisms to change, they must exist in the first place. Life began on this planet about 3.5 billion years ago by abiogenesis. Replicators, crystals that copied themselves, were the first life. Once reproduction appeared, evolution kicked in and more complex life appeared as prions, and viruses before cells and finally eukaryotic cells, the basis of all the multicelled creatures.

There is no evidence anywhere for any of the gods and gods are unnecessary in any stage of development of the universe. There is no evidence either that this planet has ever been visited or seeded by extraterrestrials. All that does, anyway, is move the beginnings of life back to the first life of the extraterrestrials.

most probable? how would we even determine the probability of 1?

3 is self evident but completely different to 2, because 2 is a claim of genesis, while 3 is simple an explanation of the speciation we see in the fossil and DNA record.

3 (though none of those words would then be very accurate for this one), given its all we have any evidence for.

Also evolution has nothing to do with th origin of life, just the diversity of it, but I'm guessing you mean to say something more like "natural processes"

There is no proof God exists.

There is no proof extraterrestrial societies exist.

So the only probably option is evolution - at least there is proof that exists.

In the beginning....God created the heavens & the earth!

No one cares whaty our theories are. Evidence is the only currency. Move on

You forgot about the spores from outer space theory
