There are always multiple explanations for any one event, both large and small, and the realm of possibility is seemingly infinite. However, there is a difference between possibility and probability. I would like to refer you to a famous philosophical device known as
Occam's Razor, which states (and I'm paraphrasing here) that the explanation which contains the fewest assumptions is the most likely to be true. I'll give you the link to the Wikipedia article on the subject:

Just because a theory sounds like a good story, or appeals to your own particular bias against authority, doesn't make it any more probable than other theories.
