I thought that was a philosophical question, all of which requires no proof. I though such question as do you trust Newton's laws of motion needs no proof. There is no way to prove the laws. We can experiment with them and show they work under our experimental conditions but still can't prove it will work elsewhere. But, if you do trust these laws, through seeing them work under various experimental conditions, you can prove many other laws with Newton's laws. I used to watch TV and I had (still have) the "History" and sci-fi channel. Between these channels I can't remember how many times some religious "scientists" were proving some events described in religious scripts actually happened, such as Red sea splitting with a desktop fan and bath tub, and bush can burn spontaneously. They got it all wrong. Philosophy needs no proof! Although it is easy to actually prove that god exists than disproving it. He just needs to show up and do some godly things in front of non-believers.
