that religion is on its last legs. First you had religion - it ruled all. Then science came (post christianity),
I think you may be mistaken, science has been around for a lot longer than Christianity... and you will find with a little research many scientists (including Darwin) who claimed to be Christian.
i'll try that again:::
Maybe they believe this because that is there daily experience. You may be certain that if you are on the moon and you drop a hammer and a feather at the same time, they will hit the deck at the same time.
For somebody who has never been to the Moon, and has never watched that bit of footage showing the experience, they know that the KNOW that the hammer will hit them on the toe whilst the feather is floating off in the breeze. They will be scientifically wrong only if you amend you question to include the stipulation "In a vacuum", and if you try to prove them wrong whilst in an atmosphere, you are going to look like a crank. (believe me I have tried to prove this to my kids, and only managed to reinforce there belief in there personal experience.)
The big problem with all of us "scientific" thinkers is that we have just as much "faith" in what we know as the next guy. I know that the planets orbit (mostly) around the sun, and can prove this is the best fit to the evidence by showing you a track of the inner and outer planets and showing how they behave differently during the year against the back ground stars.. I however cannot (without a large vacuum chamber) prove to you that the feather and hammer fall at the same rate, and having never conducted this experiment myself have to rely (have faith) that those experiments conducted by scientists that show this to be true, have been conducted correctly.
For those who believe education is the solution to the "incorrect" thinking that is expressed by those who believe in an Earth centered universe, I would suggest a great deal of care. Education has been used by many interests through history to ensure that the population think and act in a certain way. You can steer a person to think just about anything just by controlling what knowledge they are or are not exposed to. The only way to really educate people to understand science and thereby the current state of scientific fact, is to expose them to experiences that allow them to believe what they themselves have seen and felt. Anything else is just another interest group espousing faith in their chosen book.
