- It provides information on the origin of cells or organic matter, but it doesn't specify how life was formed from them.
- It does not resolve the question of how a cell could withstand a journey through space or endure the high temperatures when a meteorite entered the primitive atmosphere.
These arguments make the hypothesis of the arrival of the first cells from outer space the least accepted today.
