No you don't have to be open to that idea. And most likely doesn't cut it. It happened. 3 Astronauts from the US went to the Moon on Apollo II. Neil Armstrong stepped off the Lunar Lander onto the Moon. There is absolutely no uncertainty to it.
wow you have so much faith that stuff that happen when you were a child or before you were born is exactly what you think it is. everything one has learned in life has to be subject to revision because of the fact that it’s just easy to be wrong on things.
