If it hasn't been said yet....one word: stigmatists.
...well known fact that there have been some genuine stigmatists (not including those whose wounds are self-inflicted and/or psychosomatic) who wore the wounds of Christ. Christ is God's son. Therefor, there is a God.
But choosing a religion (that's best for you) is about another one word answer: faith. God (at least I think anyway) did not intend for you to see specific signs, magic tricks, or even miracles to get you to "hop on board". It's about believing, XYZ.
Just like almost anything in life, you need to prove it to yourself...NOT someone else prove it for you. 😉
