Sorry I know people have asked similar questions before but I’m trying to find out how we know earth is ~4.5b years old and all the explanations are like “this is a vague explanation of what radiometric dating is and it says it’s about 4.5b years old”… which doesn’t really tell me anything about how we know it’s 4.5b. It’s not like we’ve existed for that long that we can have someone confirm that yeah, it’s billions of years old.
I’m not some religious person that doesn’t believe in science but I feel like it’s normal to carry a little bit of doubt in some of these things until you fully understand it, right?? I promise I’m happy to listen to any explanation as long as you remember that I do not study anything like this so any explanation that assumes I have knowledge in this subject matter is gonna mean nothing to me 🙁
