On the divinity idea, I can't comprehend a supreme entity being bored silly one day and creating the Universe...even if it did take a week. Sorry no offence to believers...I'm not criticizing you...I am speaking about my own personal beliefs. Obviously the creation idea doesn't work for me.
So my current belief is panspermia with ET interference occasionally in our history to help out our evolution...so yes Prometheous is worth considering especially since the first Alien movie was based exactly on panspermia.
Isn't our species kind of proving panspermia if we have evolved and are now sending people and robots into space?
Also, Apollo 12 bringing back a piece of Surveyor which landed on the Moon a couple of years before them, had earth originating bacteria that survived space.
For me it seems plausible...but I still puzzle over how life began initially even if it was not here. Perhaps somewhere in the universe there are natural forces we know nothing of...or perhaps other dimensions colliding with ours.
For me it is also mind-boggling to think there's no design or architect to such a purposeful, complex, and stable system. Throughout the primordial Earth there were trillions upon trillions of simultaneous attempts for about a billion years to create a working primitive single cell. Anything that didn't lead to life, remained in the ooze. Anything that achieved stability, became the building block for the next step. Each step speeds up how long the next step takes. As an analogy, It took humans a hundred thousand years to make a single working autonomous machine, but in the following hundred years we created millions of other machines to do millions of other jobs. Each hurtle crossed creates an explosion of progress towards the next hurdle.
That said, looking at the DNA visualization shows how advanced we've become in science, but it's anything but intuitive to think that that happened randomly. Intuitively it makes me think about design (ironically the most compelling reason to consider the metaphysical I've seen).
Also, saying, 'aliens' must have helped us just replaces one question with another:
How did this complex life came to be? "I don't know"
How did this complex life came to be? "Aliens". How did the Aliens came to be? "I don't know"
...Doesn't really get us any closer to an answer. Same with:
How did this complex life came to be? "Came from Mars". How did it start in Mars? "Aliens put it there" How did the Aliens came to be? "I don't know"
