What scientific experiments have christians done to prove god exists?

First of all, there is a problem with that word "prove."  As Dr. John Lennox said in his debate with Dr. Richard Dawkins: “Of course, we do not speak of ‘proof.’ You only get proof, in the strict sense, in my own field of mathematics. But, in every other field, including science, we can’t speak of proof—we can speak of evidence, of pointers, of being convinced beyond reasonable doubt” (The God Delusion Debate).

Obviously, we can’t “prove” that God exists or doesn’t exist since He is outside of the physical realm. What we CAN do is look at the physical realm and ask, “Where does the evidence lead?” It's more like "proving" a case in the courtroom by presenting and examining the evidence and then coming to a conclusion (abductive reasoning).

It is certainly reasonable to suggest that if there is a God, He would have made adequate evidence available for us to believe that He exists. 

There is something rather than nothing (contingency argument), the universe had a beginning (cosmological argument), design is here (teleological argument), beauty is here (aesthetical argument), morality is here (moral argument), the widespread belief in deity is here (intuitional argument), etc.—what is their adequate preceding cause? Many people believe these point to God. If you are not familiar with those arguments, I would encourage you to look them up. And you can find some, like the philosopher, Dr. Alvin Plantinga who will give over two dozen arguments for the existence of God.

If you want something quick and easy to get you going, I would watch these short videos: https://www.youtube.com/playlist?list=PL3gdeV4Rk9E... 

Science is the study of the natural world in natural terms. Supernatural/spiritual realities lie totally outside the realm of science, and science therefore cannot make any valid statement concerning such realities.

What religious experiments have atheists done to prove that God does not exist?

Executed non-believers. If they rise from the dead, God doesn't exist.

Well, there was one experiment where someone was weighed just prior to death and weighed directly after death in an attempt to determine the 'weight' of a 'soul'.

None.

Healing the sick, raising the dead, prophesying, word of knowledge. This is God's type of "scientific experiment" for Believers! But we don't do these things to prove God exists for ourselves, but it is a tremendous sign for those who are not yet Believers!

What would you accept?

They hide from science, like they hide from me.

They know they can't confront either.

WE FOUND GOD OURSELVES THROUGH PRAYING...U CAN FIND YOUR OWN PROOF THE SAME WAY....TIRH not science...ONLY JESUS SAVES...U WILL FIND OUT.
