Which Came First

A computer scientist, a surgeon, and a civil engineer were gathered at the pub. The surgeon boasts, Surgery is the oldest technology in the world. It's in the Bible. God removed Adam's rib while he slept. This is clear evidence that surgery pre-dates all other technological endevors.

Without so much as a beat, the civil engineer says that before that, God formed the Earth, the stars, and everything from nothing but chaos. He created rivers, mountians and oceans. This was clear evidence that civil engineering pre-dates all other technological endevors.

No to be outdone, the computer scientist points out, "Yes, but where do you think the Chaos came from?"
