The Titanic was the largest structure on the ocean. The Tower of Babel was the largest structure on land.
Titanic was built by Joseph Bruce Ismay, and the Tower of Babel was built by King Nimrod.
Titanic was built basically to show that man was greater than the elements (some even thought God couldn't sink her), and the Tower of Babel was man's defiance against God for nations to come together and show themselves basically greater than God (they were going to use the Tower of Babel as a stairway to heaven).
Titanic struck an iceberg made by God and sank, the people building the Tower of Babel was struck by God.
The people on the Titanic were of different tongues, and the Tower of Babel was of the same language until God struck them.
The people on Titanic were separated, and the people building the Tower of Babel were scattered.
Titanic is now at the bottom of the ocean decaying. The Tower of Babel more than likely fell apart after everyone stopped building.
