Huh? As far as I know they don't even have the same letters in Hebrew so you don't make sense. And whether you translate it as
Noah or
Noa doesn't matter just as it doesn't matter whether you translate
Sarah as
Sarah or
Sara,
Hannah as
Hannah or
Hanna etc.
By the way in Hebrew
Noah doesn't exist as a masculine name at all. The masculine name is pronounced like
Noach (also the pronunciation of the name of the ark guy in the Bible) and everything that sounds like NO-a is feminine there. I love
Noah for a girl.
And the Michaela/Michael argument is kind of silly because
Michaela and
Michael clearly don't sound the same whereas
Noah and
Noa do.
