I don't get the whole Tower of Babel thing, what difference does it make? The Bible mentions Jerusalem. We know it exists. So what? It's religious significance depends on the idea that God gave that city/land to the Jews. (or the Muslims, or the Christians) How could anyone possibly know that? Jerusalem's theological significance is completely separate from its existence. Let's imagine that the 'real' Tower of Babel was found, that 'Noah's Ark' was found, that the bones of Abraham were found, or the shroud that wrapped Jesus' body was found. All those artifacts have no power whatosever to prove any single theological 'fact'.
It's one of the myths of fundamentalism that somehow, religion can be established by facts. Facts in and of themselves are inconsequental to morality and theology. Jesus died. Moses lead a group of Hebrews out of Egypt. Mohammed conquered Mecca and wrote a book. Paul fell of his donkey and had an unusual experience. Those 'facts' tell us nothing about whether religion is true, whether Christianity, Judaism or Islam are truly revealed by God.

Now back on topic. Fundamentalism is a bastard child of Nietzschean fascism serving as the ideological foundations for US capitalist elites and their imperial ambitions around the globe.
