Strong evidence? Here's something that you can try yourself; even if you say it doesn't directly prove the existence of God, you will likely say it proves the existence of higher morality, which is a requirement for the existence of God.
Try and be as good of a person as you can be for a week, even alone. Stop doing things like being cruel to others and masturbating (not assuming you do those things). Instead, treat others with forgiveness and mercy. Try to keep yourself to a high moral standard, at least for a week or so.
You may not be able to do it all at once, but you can always improve by a bit. You can refrain from insulting someone once a day (again, not assuming), and you can do something good for someone else every day.
If you try and do this, you will find that you improve as a person. Your peers start to like you more, you actually start to BECOME more wise and thoughtful. I know this from personal experience; if you look at any of my old comments you will notice that all of them lack depth or thought in any way.
If humanity was created by the sole proccess of evolution, being kind and merciful to others whilst holding yourself to a moral standard wouldn't be advantagous for the early man. It wouldn't help him survive, as it would have allowed people to take advantage of him.
This means that there is a higher morality, because if there wasn't, humans would all be murderous psychopaths. The 'Forest of Friendship'* principle of evolution not applying to humans means that the only reason we'd have morals at all is due to some higher morality.
I thought this all up myself, this isn't copy-pasted or anything. I'm saying this simply so you know that this is personal, and that I didn't just lazily google 'arguments for the existence of god'.
