Well, sorry, since the "main stream science" accepts sea floor spreading and uses magnetic striping as one of the bits of evidence, I think I'll wait for you to provide the "facts or logical doubts". Maybe you are correct, but I've never seen any evidence to support your position.That magnetic striping is more pronounced at the surface is a fact that if you didn't know it, you haven't looked into the topic. And you aren't the one that determines how much doubt about a narrative someone can have based on the facts. Thus, it's up to you to bring evidence that makes your point.
Show us your evidence for magnetic striping and sea floor spreading.
