"Yes. The Bible says He is."
A. That counts nothing for "science", since anyone can write anything they desire in a book.
B. Bible also says that God, although powerful, can't defeat an army if that army has iron chariots. I'm sure you don't believe that, do you? Yet, by your standard of "It's in the Bible, therefore it's True"...we must start teaching God is no longer omnipotent.
"And the Lord was with Judah; and he drave out the inhabitants of the mountain; but could not drive out the inhabitants of the valley, because they had chariots of iron." (Judges 1:19)
4:15 And the LORD discomfited Sisera, and all his chariots, and all his host, with the edge of the sword before Barak; so that Sisera lighted down off his chariot, and fled away on his feet.
4:16 But Barak pursued after the chariots, and after the host, unto Harosheth of the Gentiles: and all the host of Sisera fell upon the edge of the sword; and there was not a man left.
