I sure hope you went to the museum and took the tour! There is a Saturn V on display within the NASA facility. You just don't understand how big the Saturn V was until you see one up close. Seeing pictures of the Grand Canyon is similar to seeing pictures of the Saturn .... it isn't the same!
Apollo skeptics sometimes change their minds after viewing real space hardware. The Saturn sure looks big enough to heft a tiny LEM and CM/CSM to the moon.
