Be precise. There's a difference between: "Man" have reached the surface of the moon A "human" actually set foot on the moon Some doubt the first. Some doubt both. Some doubt neither. I really don't know. I can verify some things. For others I need to rely on second hand information. So I give probabilities from my limited point of view having done a good a mount of reading knowing/understanding around 50 pros and cons. Have man reached the moon 80% yes Have humans set foot on the moon 80% no
