We're always told humans can't fly, and while we think this is impossible, is it really? Humans have been trying to fly since long ago, observing animals who can fly, thinking what would happen if we could also fly. The first flying machine was created by Leonardo Da Vinci, who made a machine that could flap its wings to stay in the air, he also sketched flying machines that looked like birds and could fly like them. Though Da Vinci couldn't actually test his machines and fly. After that, many other machines were tested and proved if they could or couldn't fly, as humans grew closer to the goal; the air.
Many animals developed wings as time passed, as bats did. It is believed that bats couldn't fly and they used to be rats. Scientists say bats used to be rodents who glided through the air. Eventually, the bats' membranes began evolving and became wings, which they could now flap to gain height in the air. But humans probably won't be able to do this until a long, long time passes; so maybe don't try flapping your arms really fast, the most probable is that you can't fly.
