Question: How Is Nature And Reality Made

That’s a bit of a metaphysical one! Once upon a time there was a primeval earth (well to start with, there was no earth, it probably formed as a result of collisions of material in the expanding universe) and various elements have gradually formed from what was initially only hydrogen and helium (the two lightest elements), probably by them sticking together. This eventually led to the formation of rocks, the atmosphere, oceans, etc, all covered by a primeval soup of chemical molecules. As the atmosphere changed, it is thought that some kind of external event (eg. a flash of lightning) led to this primeval soup of elements forming some kind of primitive self-replicating molecule (such as RNA, a presursor to DNA and protein, the current recipe and machinery of the cell) became viable. If it could replicate itself, then this could form early forms of life such as single celled organisms (bacteria).

Single celled organisms eventually stuck together because of better chances of survival, leading to multicellular organisms which then started evolving by the principle of survival of the fittest (mutations to the genetic material is random, some mutations give organisms a survival advantage, so the mutation is propagated towards the progenitors). Many many many millions of years later this then led to the current flora and fauna we have on earth.

Do others agree? Does this sort of answer your question even if it’s very simplified and speeded up?
