We have science.

Edit: I really don't understand the downvoters. This specific passage was written 6000 years ago, give or take. It's from a religious holybook that has no bearing on technology, medicine, or science. Germ theory was nonexistent, most forms of medicine were in their most rudimentary levels. They didn't even have the technology or know-how for basic ironworking.
If you're an adherent to a religion, good for you. Its simply that - a mythology, a belief.
And we should be bearing no credence to the writings of religion in our sciences, unless it stated physical fact (think anthropology, geology, architecture - sciences), or if you're a religious historian and trying to understand how human religions change.
I thought we worked with sciences here, not superstition.
