But i thought the earth travels around the sun?
Yes, and?
There are multiple ways to approach. I’ll list two:
1: Metaphysical (what peacemaker is saying) that it doesn’t really means sky, etc. Admittedly, why Chazal would agree to Science on a spiritual question is beyond me.
2: Observer status: Chazal were discribing what happened as they saw it. As is viewed from someone on the earth, the sun goes around and under the earth. That has nothing to do with what happens in the greater Universe (in which the sun circles the Galacitc core, etc.). This makes sense as a viewpoint once you realize that all movement is relative anyway.
