Don't we manipulate energy all the time? It's in the form of electricity, gathering energy from wind, fuels, using tools to achieve such ends that people would call you a wizard for, had you traveled back in time and showed all the technological marvels we have done. And the mind itself is much more powerful than you think. I mean all have an aura. Who is to say that using one's aura cannot achieve certain effects. We're already achieving that, just through different means. How can someone even say they believe in gods or the force, but thinks that manipulation of any kind of force with our body and mind is impossible. Lots of things we used to think was impossible, yet people, one after another, proved them wrong.
It also depends on how it's done as using the force or magic or anything is more subtle than people may imagine and anyone who has practiced it knows what I'm talking about. If I do blessing on someone, it has taken affect. It depends all on the person being affected much like how chemicals may have different effects on different people. Some will be able to absorb energy and connect with it more easily than others. But just because one hasn't seen it, doesn't mean it didn't take affect. I mean our actions and words cause great influence. Look at all the speakers we have and musicians. They constantly influence others to inspire to feel certain emotions or feel certain things.. Who is to say uttering certain words, in a certain time and performing certain actions can't perform powers? Thing is it's not all like how it is in the movies and the problem is when people claim to do certain things, people will assume they are claiming to do what the movies show. Or like how there are fake psychics even though there are real psychics in the mix and you have to find the right one.
I have witnessed certain psychokinetic events, rituals ect. And know they are all very real. I know some who claim such powers can be fakes, but it isn't wise to dismiss it as all trickery. Powers are usually known by experiencing and cannot all be observed through a microscope. And that also shows that because one does not see it it doesn't mean it isn't there. We can't see germs without a certain lens. Does that mean germs never existed until we found them? No they were always there. We needed a certain lens to see it. And the third eye is often the "lens" you need to see things your eyes can't see.
I sometimes think that a disbeliever will not believe it in because one may not want to even if it is in front of their face. Even if they know deep down they have experienced things that no text book could explain or any science teacher could touch on. Because the idea of people having certain powers scares people. Wouldn't it scare you to know there may be people who can use certain abilities, to manipulate others and could use them for good but also ill will, and that there are dimensional beings one cannot even see directly but know deep down they are there? I think it may scare some others because certain things are not what people understand or want to understand and so they may call them crazy because they don't know what else to call them when they hear something not of the status quo and goes beyond their level of comprehension. I'm not going to pretend every single thing in the bible and other spiritual texts is 100% correct because it isn't. Some are exaggerations or just lies but there is some truth to this. Can't pretend everyone who claims such powers is telling the truth because some do lie and make stuff up, but that doesn't mean the power does not exist just because that person cannot wield it.
