Soap? Chemists?

LOL, we had soap before there were chemists. You wouldn't have the chemicals without the engineers. No pipes, no mining equipment, no oil wells, no processing equipment, no labs, nothing. Second place, but still a long way ahead of doctors.

I think we had soap long before we had chemists.
