stars from up to 10 (or more) billion light years away. So, light had more than enough time to get practically everywhere well beyond range of naked eye.

10 billion years is a hell of a ditance taking into account that naked eye can barely see brightest stars to about 1000 light years away only - so what we see in night sky (our neighbor stars only) is just 1/10000000 fraction of all stars of our home Milky Way galaxy alone.

So, if you are just slightly away from any galaxy, there are practically no stars on your sky - only very dim and rare galaxies.
