Under normal circumstances that would be impossible, zircon crystals strongly reject lead atoms as they form. There's no way to stuff lead into the crystal lattice in the quantity we find them there. But uranium and zircon go together just fine, we just have to wait for it to decay into lead. The trouble is it takes ~4.5 billion years for just half of those uranium atoms to turn into lead. So any zircon crystal we find with half as much lead as uranium must be roughly that old
But that still doesn't change the belief that a creator could have created the universe in whatever state it currently exists in. That's why these arguments never go anywhere with hard core young earth creationists. It's also not worth the energy arguing with them because they often believe that anyone trying to convince them otherwise is an antichrist trying to lead them astray.
If God created it in that state then they should be curious to understand that creation. They look at rainbows as the beauty of creation but not the fact that lead exists in these crystals. It's all equally beautifully complex. So why not try to understand it.
If God made the world look like it was created billions of years ago there must be something worth learning from that, even if you believe it was snapped into existence 6000 years ago.
Tbf for your specific example, rainbows are specifically mentioned and "explained" in the Bible. After drowning all life on Earth except for Noah and a bunch of inbred animals, God sent the wainbow down as a pwomise that he would nevew do it again 👉👈
It doesn't. It was never the point of his post. You can still believe that if you want. His reasoning for why he doesn't is outlined there.
It comes down to whether or not you find processes that we have researched and documented time and time again to be compelling evidence, or you want to believe it is a practical joke (while reductive, it is pretty much that argument breaks down to being).
Is that what were doing now? Regurgitating stereotypical insults on a post where the "pro science" side dropped the ball and leaned on a ridiculously stupid misunderstanding to disprove something stupider?
