What is the opposite of atheist?

i don't believe in any specific religion because no religion can be proven to be right or wrong but i am not atheist because that also can not be proven right or wrong. i believe being open minded to every thing is the most rational because any religion or lack of supernatural cause for our existence can be true. a creator of any kind can very well be true, whether it be god/gods or even the theory of aliens involvement, or scientific, big bang or evolution, can be true. the point is, there is no proof for me to sit back and say it is this way or that way because there is no proof behind any statement that i could make. basically accusation without fact is meaningless which, to me, applies to all things that can not be proven. so if atheists believe in nothing that they can not see or touch and can not be proven then what is someone who looks at everything that can not be proven with an open mind and believes any thing is possible?
