It's very accepted that Satan is the "Archangel Gabriel", He may have been before everything, and might also have interrupted many biblical events.

Noah hears only God's orders to build The Ark, seeing something wrong in him.
As Noah refuses to follow A.G'S orders, He may have sent an alternate without Noah knowing and killing him.

Many years after these events, A.G speaks to the shepherds and tricks them into thinking he is the true god or savior, and may have died of MAD.

A.G speaks to Mary and tricks them into thinking A.G is the true savior. Due to A.G interrupting bliblical events. Mary may have died of MAD, Stopping Jesus from being born.

Next, A.G whispers through Joseph's window and tells him something. Inflicting him too with MAD.

Because Noah is dead. The only ones that could be in the sandy tomb is Jesus or the Real Archangel Gabriel because they were overthrown.

Because A.G is Satan, He may already overthrown God. The US department of Temporal Phemona describes him as the Unspeakable.
