Use the same protocol you use to communicate with your wife and children.
Use the same hypothesis to test the existence if your wife and children. I tested this way and you too can test using my method too, as I was once an atheist: I told to God that if He did really exist, I will ask a question to You so personal to me which is not known to anyone and I will go to a "so called" preacher or pastor to pray and the answer for that question must come from his mouth. This happens not once, twice but every time I go and pray to any preacher who is godly - I even use this to test if the preacher is truly from God or just a false deceiver. The key is this: Bible says, no one knows the thoughts of your mind except God - not even the devil knows what a man thinks. A good example can be found in Dan 2. How can someone tell you what you were thinking yesterday which bothered you much but today you totally forgot what you were thinking yesterday? This hypothesis to test the existence of God is not just to test the existence of someone who can communicate to you back but God who created you who knows the thoughts and even the imagination of thoughts - all you must have is a genuine desire to know the truth.
Once you get the response back, you will know the truth yourself. The reason I just stop here is because, most people in Christianity refuse to believe in Evolution and believe in God, is not because they are silly and non-thinking superstitious people BUT they have a "personal relationship" with God who is their Creator. Christianity is all about "personal relationship with God" and a relationship is never one way. Some who have experienced this relationship, knows for sure that there is a God who created everything by standing firm on the Bible truth. Some Christians who also have experienced a personal relationship but starts wavering with the push from evolutionists and "so called" convincing evidence, will start to sacrifice the Bible truth to slowly twist Bible to fit evolution. It also depends on how much they know and have faith their Creator to believe in evolution or creation.
I can argue for ages and I can never convince you UNLESS you experience this "personal relationship with God" yourself. It all starts with a humble and simple prayer from deep within your heart with a genuine desire for truth and I am sure He is eager to respond you back. Once you are already communicating "not one way as just name-sake prayers" but a "both way with Him responding to you", how much do you think that you will push for evolution and how much will you hold on to the Bible?
Hope you understood my message and desire for you to know the truth yourself. I can never teach you the truth, but He will but ONLY if you have a genuine desire for it.
