No offense, Chatty, but you are looking at reality through the grid of your world view. If you put down the grid, then facts won't pass through it like water through a colander. The supernatural's influence is observable through the natural universe. Is there not a saying that you can tell a painter by his painting? Let me put it this way: If some mold was sitting in your fridge and it looked like mush, then you can not assume that it was designed. But if it had multiple colors and looked exactly like Albert Einstein's face, then you can be certain that it as designed.
Take another example. Suppose you were walking through an ally when you found a trash heap against the wall of the building. It looks like it was just thrown there, so you cannot assume that it was intended to be a grand observance to others. But if the steel pipes, stray screws, and other junk was put together to look like even a moderately impressive model, then you can be certain that it was designed for somebody's pleasure. Now take that example and apply it to our own world.
Our atmosphere had to be fine tuned to an exceptional degree or else life would not be able to exist, and if our earth were any closer to or further away from the sun, then life would not be able to be sustained, either. Not to mention that the planets keep the earth in proper orbit. Just these observances alone are powerful indicators that there was an intelligent being behind the universe' assembly. Now just consider that we humans have eyes with which to see the observances and others of extraordinary beauty in the world around us. Even earth's creature's drive to self-preservation indicates that the intelligent designer is a benevolent being who enjoys watching His creations flourish.
