| There are two that I like. I have mentioned them before:
1. Energy from the sun allowed for the organization of inorganic molecules to for reproducing molecules (i.e. living molecules) This has been reproduced in experiments.
2. Spores from an asteroid landed on earth and viola! Life.
The first has descent info backing it up. The second not so much. But I like it all the same. Very science fiction like, even though it sounds like it is from a movie it is very probable. |
