"Jehovah" is a pronunciation that has evolved as a result of time, multiple translations from one language to another, and an ignorance of the Masorites inserting vowels for alternate, substitute titles.
"Yahweh" is not a title, rather it is the creator's personal name. It means "I AM WHO I AM" and is His name FOREVER (Exodus 3:14-15); it does NOT mean "Lord" ("Baal" = "Lord") and "God" is the exact pronunciation of G-a-D, the false deity spoken of in ISAIAH 65:11 sometimes translated as "that Troop", "Fortune" or "Fate".
Why not simply call the creator by His actual name?
Literally means, "I AM."
It should be noted that God declared Himself to Moses using this name, and Jesus also declared Himself to the Jewish officials using this name.

"Jesus said to them, 'Most assuredly, I say to you, before Abraham was, I AM.'"
