I don't know if you have read the Buddhist scriptures, but there is always a saying: If I heard them, these four words were recorded by a disciple Ananda when the Buddha was lecturing. The Buddha said to Ananda, you should add this sentence to let future generations know that this is not a lie, but what you really heard, so as not to make future generations suspicious. Some are recorded by Ananda, some are not, and I haven't touched them all. But it is very important that Buddhists will go to hell if they talk nonsense. They all have rules, so the truth is credible. We are skeptical because we haven't reached that level yet, just as we can't figure out a rule after being hit by apples thousands of times. I hope I can help you.
