I find it somewhat strange that people still believe the name was yahweh.

Because of the waw (vav) letter in it?

No one who values the tetragrammaton enough to call their family or company by it would have the gall to do so.

Jesus who was here from the beginning referred to the creator as Father so I'll stick with that.

The God of the Old Testament was a killing God and told his followers to kill as well like when they were claiming the "promised land." Have you ever wondered why "God" stopped killing after Jesus appeared? Because The Father never started killing except in jewish legend. It is no wonder that Judaism is known as the death cult.
