How did life start.
The first is that life on earth came from space. Which sounds fantastical, but it's not totally sci-fi. There's some evidence that biological molecules are present in asteroids and it's been suggested that space rocks brought life to earth. There seems to be mounting evidence that this is at least possible . The more intuitive idea is that life ...

Evidence from the first life on Earth is scarce, so the hypothesis will likely never be conclusively proven. Instead, by exploring what RNA is capable of, scientists will gradually better understand whether the hypothesis is a likely or unlikely explanation. The RNA World Hypothesis also has its detractors.
The Big Bang theory, developed in 1927 is considered the most credible scientific explanation of how the Universe was created. It suggests that through a process of expansion and explosion hydrogen gas was created which led to the formation of stars, and their death (supernova) led to the creation of life.This origin-of-life theory was first proposed by Charles Darwin.

Clay minerals, he explains, are crystals formed from the weathering of rocks by water. And clay, like any crystal, grows by itself-- think of crystals of frost expanding on a windowpane. Crystals, in other words, self-replicate. So if self-replication is the key, life did not start with organic molecules. Life started with …
