Why don't atheists believe in witches and witchcraft?

ok so many of you wont believe me but i am a witch (no not like harry potter do some research on wiccan witches then come back and answer) and i have noticed atheists only believe on things proven by science which is kind of dumb because science hasn't proven everything they never will but they will get further anyways heres what i wanted to get to why don't they believe in magick? i mean by definition magick is an act that influences change for example a ritual that would send out energy into the universe and cause an effect. magick is the use of energy to cause that change controling that energy with the mind so here is the point science believes in energy they say energy cannot be created nor destroyed only transfered so why don't you believe we use our mind to transfer that energy to the universe and influence change? 90% of the mind isn't used so we only use 10% the other 90% has potential beyond comprehension so please don't say the mind cant do that because no ones knows that for sure so why don't they believe i don't write this to make you believe just to see why you don't believe. and scientists say prove it but what they expect us to prove isn't what we can do but what we cant for example we can influence change in many ways but they expect something like harry potter and hollywood this is impossible to prove. finally i want to ask why don't you believe and why don't you accept that it MIGHT exist? finally for all the ignorant people no we aren't devil worshipers or believe in "satan" i have used magick and have never had a pact with satan so don't say its evil or satanic. thank you for your answers and please reply in a non ignorant way
