One explanation of life's origins suggests that meteorites gave way to life on Earth. Which of the following provides evidence to support this idea?

Organic molecules form in Earth’s atmosphere and travel through space in meteorites.
Some meteorites contain organic compounds which may be precursors to today's living cells.
Vesicles in meteorites and microspheres can maintain an internal environment and store and release energy like cells do.
Meteorites contain full DNA molecules, which self-replicate and pass onto future generations.

Biologic molecules - vesicles, DNA etc - have certainly never been found on a meteorite. The conditions in space are too harsh for them to form. Organic compounds have been found on some meteorites - but they don't come from the earth's atmosphere...
