It's important to listen to other people's opinions and what they believe. You should never discredit someone's idea solely because it goes against what you believe you should keep an open mind. None of us know everything so none of us can say beyond doubt that our ideas are correct and their ideas are wrong. That being said there is not multiple versions of the truth there is what is right and everything else. However we should not be so arrogant to assume that we know exactly what is right. Have evidence and reasons for what you believe and listen to others evidence for what they believe, if it makes sense and they don't have holes in their logic and evidence then consider and look into it more. You may find out that they are right or that you stand by what you believe or it could put you somewhere in the middle. It's important to learn from others and keep your mind open but it's also important to stay strong in what you believe. God is the truth and the Bible is true, use those as standards to judge everything else by.
