It's interesting that everyone is looking at the same evidence in nature but coming to different conclusions. Sometimes you need to ask yourself what evidence would you need for the existence of a Creator? Is there any possible evidence that could provide for the existence of a Creator?
What if a theoretical Creator wrote a letter to you saying what his name was (Psalms 83:18) and told you he was responsible for creating everything (Genesis 1:1). How about if he gave an explanation for things like why we suffer (Genesis 3:6), he explained how he was fixing the problem through his kingdom (Mathew 24:14), and that his purpose is for a future without suffering (Revelation 21:3-4). What if he made it clear he was the author of that message by stating it (2 Timothy 3:16) and then showed the ability to predict the future by showing the rise of world powers followed by his kingdom (Daniel 2:44). Certainly if someone made those claims I think it would at least be worth investigating.
According to that Creator it's possible to get more personal evidence. He claims to hear prayers (Psalms 65:2). He will answer prayers that are in harmony with his will (1 John 5:14-15). It's his will that everyone learns the truth about him (1 Timothy 2:4). Putting those ideas together, my theory is that if you pray to him he will provide the evidence and knowledge you need.
