Every religion is poison for the brain. Believers believe the words of religious leaders and are not able to analyze the words and actions. If the Patriarch goes to the Mercedes S class then how can you believe him about what the pursuit of luxury is a sin?
Scientists make up science theories. Some of these theories are evolution, relativity, big bang, and black hole. No body knows if these theories are factual or not. If they were factual, they would become science law, and not remain theories.
Some scientists and the media say that some of these theories are factual. But these theories are not known to be factual. We can tell that the theories are not factual, because they are science theories, not science laws.
When people believe and trust that these theories are factual, because they believe the scientists and media who are lying to them, this part of science has become religion for them. So, as you say, there is religion that is poison for the brain. It is science religion.
But you can't believe that life and the universe exist. They are nonsense. The only, Only, ONLY understanding of how they can exist is the fact that they do exist. Since nothing scientific comes close to expressing how they can exist (big bang and evolution are hollow lies). The absolute best we have for understanding life and the universe is the Bible record.
