Researchers find that ribose, the 'R' in RNA, could form naturally in space

This pushes the idea of Panspermia. Which is to say that creationism believes god did it. Science says there is a possibility that life started from the basic building blocks provided by comets as well as the water on Earth or that the other possibility was some alien life form seeded the galaxy with life.

I tend to think it was the comets. Even there, life has a hard time finding a place to take root. But once it does, it does so with a vengeance. The Earth is permeated with life. From the air, to the lowest points in the ocean, to inside rocks, life is found.

 I think it's not necessary the life elements to come from the space, because that time the Earth was something like the comets now (without air, without life, with a lot of radiation, etc.) And even the life's elements (or some of them) came from the space, it's not a valid argument that they're 'Made in God-land'. The opposite -- it's a serious issue for those, who believe the religions, that postulate that God created the Universe (everything) in 6 days.
 If the Alien life form seeded the galaxy with life, then it's again, not an argument that this Alien life was God-made.
 I never thought that it's an interesting question (where exactly the life began/begins -- on Earth, on a comet or somewhere else). For me the most interesting question is how exactly it began/begins and what's its real essence + how to fight the death.

To me the interesting thing is exactly when did it change from chemicals to life. Conditions were not right at the start when the Earth was going through it's cometary bombardment as the solar system cleaned itself up. As you mention there was no oxygen. It took a long time for the reactions and one celled creatures to create enough oxygen to start the plant life. Even then plant life was not as we know it today.

I liked the Oparin's work about it. I'll link here this: https://en.wikipedia.org/wiki/Alexander_Oparin#Theory_of_the_origin_of_life
