Neil Armstrong was the first man to step down onto the surface of the moon. Here’s an old filmstrip from 1969 when he spoke his most famous words:

Here’s another great quote by the astronaut that’s even more thought provoking:
“It suddenly struck me that that tiny pea, pretty and blue, was the Earth. I put up my thumb and shut one eye, and my thumb blotted out the planet Earth. I didn’t feel like a giant. I felt very, very small.”
— Neil Armstrong
