Easy arguments against the Bible, and religion as a whole

[Jackalope]

i'm not talking about any of that. how about after all the expansion once the universe is at it's state and the stars around the universe are created, how did light from those stars 40 billion lightyears away reach us?

There aren't stars from 40 billion years in any direction that's viisble to us from the earth.
The farthest source of light (a galaxy) that we can see is just over 13 billion light years away (something like 13.2 billion LY away).

In case it's not apparent to chipan - that galaxy appears to us now as being 13.2 billion light years away, however, we are seeing it where it WAS billions of years ago, not where it is now.
