1.Speculate about how reasonable you think these theories are. Are the events that formed planets, biological molecules, and cells probable or improbable? Explain why you believe as you do
2."Living things reproduce" and "Living things inherit traits through their genes" are two characteristics of life. Apply your knowledge of cells and heredity as you think of what other molecules and biological processes would need to be present in order for a protobiont to be considered a living entity.

Life happened, therefore life must be reasonable.
> Are the events that formed planets
Very probable. We're not the only solar system to have planets.
> biological molecules
Very probable. Simple amino acids, lipids, even nucleic acids can be formed in a reducing atmosphere through physical methods (e.g. lightning).
> cells
Unlikely, but it happened!
> what other molecules and biological processes
You'll need a cell membrane, pathways for metabolism, and a method for self-replication.

Um, we'd have to see what these theories are.
