Reason 1 - Treating theories as 100% verified facts/laws
Remember, a theory is not 100% verified. A hypothesis with evidence but not 100% proven is a theory. Once it is 100% proven, it is a Law.

- Gravity is a Law. It is 100% proven. Hence we call it the "Law of Gravity". Even defying gravity doesn't disprove gravity.
- Evolution is a theory, hence we call it the "Theory of Evolution." Not 100% proven but very good evidence to support it. However, there are gaps in the evidence.
- The big bang is a theory, hence we call it the "Big Bang theory."
Science is about observation. We observe what we can and try to determine why something happens or happened or how it happened.
We don't have to understand laws fully. While Gravity is a law, we can't yet explain how it works.
REASON #2 - To the lay person, science is just another religion.
In a religion, a very wise and righteous person sees something amazing (vision, God, taken up to heaven, whatever) that the average person could see if only they would be righteous enough. They call them a prophet. The prophet "preach" to the masses to get them to believe. The average person has to "trust" the prophet. The average person never gets the amazing experience but is asked to think about it and believe. Certain believes become so indoctrinated that they become zealots and lose rational scientific thought. Teachings are misconstrued by religious zealots.
There are a few very wise people who have seen something amazing that the average person could see if only they would be rich or educated enough. They call them scientists. Scientists "preach" to the masses to get them to believe. The average person just has to "trust" the scientists. The average person could never go to CERN and witness all that is happening there, but they are asked to think about it and believe. Certain believes become so indoctrinated that they become zealots and lose rational scientific thought. Certain believes become so indoctrinated that they become zealots and lose rational scientific thought.

REASON #3 - Using theories to disprove something they don't disprove (Usually by misconstrued scientific zealots)
I firmly believe in the the theory of evolution. We have evidence of changes in species over time. We still do not have proof that evolution was the result of an outside influence. We do, however, have evidence of evolutionary jumps--jumps meaning evolution that occurred faster than scientists suspect would be possible, hence there is the possibility that some outside influence gave evolution a bump. Contrary to popular belief (by scientific zealots), evolution and intelligent design and not contradicting theories. DNA looks like biological code and the way it is used in different species looks a lot like good code reuse or self-learning biological code.
The point is, claiming that the theory of evolution disproves intelligent design, or God, or some higher power, is not scientific. There is little correlation between the two ideas. Scientifically, God and evolution could both exist. God (or ancient aliens or a powerful race from a different dimension, or some entity outside of space and time, whatever) could have created the world/universe, whatever, and uses these scientific laws to do so.
Science observes and makes hypothesis, tests them, forms theories, and hopefully discovers scientific laws. It doesn't make brash statements that evidence for one theory disproves a completely unrelated theory.
REASON #4 - Science ignores the unexplained or calls the observer a liar.
Here is one example, but there are many more . . .
A person has a spiritual experience. Their mother returned to them as a spirit and gave them a bit of wisdom. Science scoffs at this experience and calls it untrue. Why? How could such a thing happen? How does a spirit of the dead visit the living? It is not explainable by science, hence it must have be a lie. However, science is about observation. The only scientific evidence that exists--the only observation that exists--is by the person who had this spiritual experience.
Hence by proof of observation, there is an extreme amount of evidence that people see spirits. Now, multiply this by the millions of people that have this experience and the scientific evidence--human observation--of people seeing spirits overwhelms the evidence of other theories, such as the theory of evolution. But such evidence is ignored. Surely these millions of individuals were all just lying and making up anecdotal experiences for one reason or another. Liars.
If a person has such an experience, and science says they are liar, how do you think they are going to feel toward science?
Then when a scientist does take such an experience seriously, the rest of science calls them quacks.
REASON #5 - Using very small amounts of data
Statistically, we probably don't have and will never have enough data to prove global warming is causes by humans. Science is doing its best. It is looking at ice core samples, and guessing the weather in the past. We are tracking data now. We don't have data except for a small portion of earth's history. We have barely 100 years worth of data. Scientists estimate the earth is 4.5 billion years old. 100 years is such a small percentage of the earth's existance. 2.2e-8 by calculator. That will never be a large enough of a sample size. And while ice cores lead to guesses about past weather, they still don't increase our sample size enough.
