How Did People Get To Planet Earth?
The most commonly accepted theory is Darwin's theory of evolution, which suggests a molecule, by chance, was formed which was able to replicate itself. Sometimes it mutated and the strongest variations of this molecule remained. Eventually it formed single-cell organisms, which became simple animals and plants, which became the wealth of biodiversity we know today.
In layman's terms, all life on Earth grew up from 1 invisible blob that made itself by chance.
