It is the best explanation because it is a culmination of many scientific investigations.
It is an educated guess that has been voted on by the majority of the scientific community.

A scientific theory is a well-substantiated idea and opinion which explains the natural phenomenon. For a theory to be a scientific theory has to be:
1. well supported by the observations and experiments.
2. supported by repeated experiments and hypothesis.
Since in the question the scientific theory was proposed by more than one scientists who performed many experiments after Dalton who proposed the atomic theory. These scientists modified and revised the theory with their discoveries like JJ Thompson discovered electrons, Ernst Rutherford discovered protons and James Chadwick who discovered neutrons.
Charles Darwin used domesticated animals to provide evidence for evolution by natural selection by showing "<span>Differences between breeds show that selection can cause species to change."</span>
By the beginning of the 20th century, researchers thought that plastids and mitochondria could come from bacteria. These would have been ingested by primitive cells and live within them in symbiosis.
