"I looked and looked but I didn't see God."
— Attributed to Yuri Gagarin
"For what can be known about God is plain to them, because God has shown it to them. For his invisible attributes, namely, his eternal power and divine nature, have been clearly perceived, ever since the creation of the world, in the things that have been made. So they are without excuse."
— Paul the Apostle
But my point in bringing this up is that the scene I quoted from is a good illustration of preconceptions. We all have them, though many people do not know it, or even try to deny this basic fact of life.
Even scientists. Throw away that image you have (your own preconception) that scientists are completely objective and unbiased. Instead of following the evidence wherever it leads, they have a preconception of what they want to prove. That can be a good thing when a scientist is saying, "I wonder if this will prove that I'm right about the effects of bicycles on rainfall", or something. It's a bad thing when they start out with an attitude of forcing the evidence to fit into a box at all costs.
You see, science is supposed to stay with things that are measurable, testable, repeatable, falsifiable, etc. When scientists venture into the realm of philosophy, they leave true science behind. What gets confusing is when people will move back and forth between science and philosophy, thereby proclaiming their philosophy as actual science.
Some areas of natural science have preconceptions that contaminate evidence and observations, including:
- Philosophy is fine as long as it is pro-evolution and anti-God
- Evolution is true, even though we do not know how it works
- Evidence from any kind of "believers" should be rejected in most cases (the logical fallacy called "poisoning the well" applies here)
- Only matter (material) and energy exist
- God does not exist, no do spirits, angels, Satan, demons or anything that is non-material (but it is illogical to attempt to prove a universal negative)
- Science (or evolution) has disproved the Bible (astonishingly stupid and ignorant, making an assertion and expecting it to become true)
- Miracles do not occur, did not occur, and can never occur (very presumptuous, don't you think?)
- Intelligent Design, as well as Creation Science, are religion
Both unbelievers and believers have presuppositions, our starting points based on our worldviews. Theirs is usually based on materialism or naturalism, and ours is based on the revelation of God in the Bible — and they hate that. Since the Christian is supposed to please God rather than men, the foundation of our thinking in every area is the Bible.
The "Brian Griffin" quote at the top and the Yuri Gagarin attribution show a common preconception, that God is a big, grandfatherly man with a beard that can be seen better from space. If someone is going to seek God, it is best to drop the above preconceptions and biases. Then, honestly consider that he may be there after all. But he does not have to play by your rules; God has already been made known (John 1.18, Rom. 1.20).
However, knowing that God exists means that he's the Creator, and we should find out what he has to say. That involves swallowing too much pride for some people.
This applies to evolutionism as well: Perhaps it is not true after all, that evolutionism's critics and the scientists who have abandoned it may be correct in doing so after all.
