From the following, can anybody tell me where I am going wrong in my thinking?
Cosmologists tell us that our telescopes can detect starlight that left a star 13.4 billion years ago. I say that is impossible for the following two reasons:
1. The Big Bang occurred 13.4 billion years. At that time, there were a lot of sub-atomic particles and emerging gas but no stars. Without the existence of stars 13.4 billion years ago, there could not have been light that left a star at that time and which traveled in that amount of time to reach our telescopes today.
2. At the time the Big Bank exploded into existence. the "stuff" that eventually coalesced into our Earth (let us call that the "Earth Stuff') and a given star (let us label that star "Star X") came into existence at the same time. The light from the "stuff" that made up Star X reached and then flew past the Earth Stuff about 13.4 billion years ago. Thus, today it is impossible for our telescopes to see the birth-light from Star X since that light flew past the Earth Stuff long ago.
