Why?
No
How?
Maybe
Science doesn’t answer the Why?* questions. Philosophy does.
Are we a brain in a jar living in a simulation? Are we creation of God? There isn’t an experiment that can test those hypothesizes.
* Why? has different meanings and science does answer some of them and the one that I assume you are asking is one of them that it doesn’t.
