You need Proof, ok
First of all you have to agree on two things
Man cannot create or destroy anything. What he can do is, he can change the state of something which is present on the earth into another state. For an example, take the phone. It is made by a man I agree. But he didnt create it. He just took the raw materials which is present on earth to make it.(plastic, sand, iron etc.., ) He also cannot destroy it(if he break, it will separate into pieces, if he burn those pieces that state would turn into liquid) So we come to know that a man cannot destroy or create anything. Only can change the state.
Second, a thing cannot be created by itself. Take the same example, the phone. Can you say that the phone itself made it. If someone says that we will call him crazy. So someone who is superior than us has made the phone. But We dont need his name or we dont have to see him. But we accept that there is someone who has surely made it. that is a simple logic.
Now do you accept the facts above ??
