Occam’s Razor, Suppose there exist two explanations for an occurrence. In this case the one that requires the least speculation is usually correct.
Example: Two trees have fallen down during a windy night. Think about these two possible explanations:
1) The wind has blown them down.
2) Two meteorites have each taken one tree down and, after striking the trees, hit each other removing any trace of themselves.
Even though both are possible, several other unlikely things would also need to happen for the meteorites to have knocked the trees down, for example: they would have to hit each other and not leave any marks. In addition, meteorites are fairly rare. Since this second explanation needs several assumptions to all be true, it is probably the wrong answer. Occam's razor tells us the wind blew the trees down, because this is the simplest answer therefore probably the right one.
Appears you have chosen a scenario somewhat less credible than example 2.
