Can you see someone two miles away?

My girlfriend and I have a bet running. I say we can see a person that is two miles away, and she says no way. Also, you must be able to say that a person is. Let's go out and prove it, but first wanted to see what you think. Therefore, one can see a person that is two miles away?

Assuming perfect weather conditions ... A person 5 feet tall at 2 miles (10,560 feet) appears: tan ^ -1 (5 / 10, 560) = 0.027 degrees, or 0.027 * 60 = 1.62 arc minutes tall This site - claims http://www.michaelbach.de / ot / lum_hyperacuity / index.html normal human visual resolution to be about 1 minute of arc, so that a human being at that distance would be 62% higher than the minimum that can be seen. This does not necessarily mean that you could tell he was a person, but would be able to say is not just a point. Note If this test on flat ground the curvature of the earth will come into play. Need a of people to be on top of a house or something. You get:)
