Each time I say "G5" I mean "5G". Sorry about that! Is the earth flat? Is 5G is a mind-control experiment by the Russian government?

Instead of giving you a long and mostly useless philosophical lecture, I will tell you a simple criterion that you can apply for most cases, which is that scientific models are the ones that explain lots of observations with few assumptions.
