So, basically you are saying that the religious community is full of bovine excrement for believing that faith can move mountains?
Nope. I'm just saying that believing something does not make it so. It is possible to believe something which is true, and it is possible to believe something which is not true, and it is also possible to believe or disbelieve something which cannot be (or at least, has not yet been) proved to be either true or false.
As far as how I feel about the specific question of faith being able to move mountains, again it's a figurative statement, not literal. I doubt very much that even my Grandma (a dyed-in-the-wool hardcore south Texan Pentacostal) would claim that her prayers could cause a major geological feature to change positions. That would be the literal sense, and yes, I would consider somebody who claimed that they could do that to be quite loopy--unless they could prove it.
In the figurative sense, though, the saying that faith can move mountains means only that belief in your cause or in yourself is very important. If you believe that you are destined to fail in a given endeavour, chances are that you will fail. If you believe that you can succeed if you try hard enough, chances are greater that you will succeed. But of course, no amount of belief in yourself is going to change anything externally to yourself. Only actions can do that. If you believe you can succeed, you're more likely to take those actions.
And, just to be ornery. I'm sure you wouldn't disagree that the time will come when airplanes will fly through the skies of Mars...even though the atmosphere is about 1/100th the density here on earth.
Provided we last long enough as a species to make it there with the capacity to do that, sure. No problem. I'll stipulate that this could one day happen. That has nothing to do with humans flying by flapping their arms though.
But what about flying through the atmosphere of Saturn or Jupiter where flying, (by your definition) may very well be possible by ornithoptic arm flapping.
Not unaided, no. An ornithopter needs something to flap, yes, but it does not flap human arms unless the designer is a serious sicko. A human can no more fly by flapping their arms on Saturn or Jupiter than on Earth.
I would not be too quick to pooh pooh the "perpetual" dreamers. They do provide the service of making us question just how and why their schemes wont work. I'm reminded that even a broken clock tells the right time twice a day.
A broken clock is right twice per day only by coincidence. If that's the best reliability that's on offer, I'll pass.
I don't pooh-pooh the true dreamers. I am simply skeptical of unsupported claims, conspiracy theories, and people whose argument about why their particular scheme will work boils down to no more than "it really seems like it should work".
When there is a well-understood and easily demonstrable reason why some idea will not work, I see no point in supporting that idea.
