It depends on how much rigour do you expect from a proof. So, it is effectively proven that electrons exist and behave as we currently know them to behave, but perhaps more evidence will come to light that they behave differently from what we currently know, and then we may decide that the concept of an electron is no longer accurate.
Once again, you are misconstruing my argument. I
Religion however cannot prove anything, true or false. In fact the whole foundation of religion is faith, which is the belief in something in spite of a complete lack of facts, evidence, or reproduceable results.
