You can reflect lazers of off the moons surface, ergo we have certanity there is a non natural thing on the moon. So yeah we have.

Mythbusters have done this.

we've landed don't worry

The flag was a standard 3-foot-by-5-foot nylon flag that was altered by sewing a hem along the top. A telescoping crossbar, hinged to the flagpole, was extended through this hem so that when the flag was planted on the Moon, it would stand out instead of hanging limp against the flagpole (as it would normally do, since there is no wind on the Moon). When the flag was planted, astronauts Neil Armstrong and Buzz Aldrin had a little trouble getting the telescoping crossbar to extend to its full length, and so it ended up being a little shorter than it should have been. As a result, the flag was bunched up slightly and looked like it was actually "waving in the breeze."
