Maybe not infinite, but so far that you cannot easily write a number that large. At least billions of light years, where each of those light years is 6 trillion miles long. (A light year is a distance, not a time. It is a distance of 6 trillion miles.)

Perceptible atmosphere is about 50 miles thick. You can orbit without significant air resistance at 100 miles altitude above the geoid.

Depends on the time of day and the weather, during a rainstorm it can be less than a mile, on a clear night, could be billions of miles.

If you mean how far can you see at night, then the answer would probably have to be in the neighbourhood of 2 million light years this is approximately the distance to M31 in Andromeda, this galaxy is visible to the naked eye on moderately dark nights.

Roughly about 20 miles, after that its outer space you would be able to see.

"Miles" is not a big enough unit of measurement. Try billions of light years, about fourteen of them.

All there is. Eyesight is not limited to distance.
