When one looks at the world around us, any mature person can easily see that it could not possibly have come about by natural means only. This is why most people in the world reject the concept that everything has arisen by natural forces only and believe in some sort of force beyond nature.
And this is despite the intense propaganda in modern societies that currently pushes a nature-only agenda. Thank God that common sense prevails on this subject.
You are affirming the consequence here. Statements like yours and "If the universe had been created by a supernatural being, we would see order and organization everywhere. And we do see order, not randomness -- so it's clear that the universe had a creator." are fallacies of logic.
The reason some are confused by your claims to be a science lover is that a scientist would never kick back and say "common sense tells me so I'll just leave it there." They instead test and attempt to falsify their own and others' theories to determine the best explanation.
The common sense of mature people is, unfortunately, a poor guage of truth. Please remember that the common sense of mature people once thought that flies came from rotting meat and that the earth was the center of the solar system. I can just hear them now, saying, "When one looks at the sky, any mature person can easily see that the sun is obviously moving across it. This is why most people in the world reject the concept that the sun is the center of the solar system. And this is despite the intense propaganda in that currently pushes a sun-centric agenda. Thank God that common sense prevails on this subject."
Have you ever seen one of those pendulums with the sand at the bottom for sale in the Museum Store and elsewhere? When you release it, the tip of the pendulum will slowly trace out a beautifully symmetrical pattern. I wonder if you showed this to someone before the time that we understood complex harmonic motion what their common sense would tell them.
But all of that is just conjecture on my part. But still, complexity does not logically require intelligence. So if we want to discuss why things are "complex" (I'll leave aside for now the fact that most life on earth is single cell), we can't do so by making these kinds of affirmations.
