Can we really know anything for certain?

Welcome to the debate arena! Today's topic: "Can we really know anything for certain?". Your opponent's style: Devil's advocate

No we are constantly discovering new things, evidence and furthering as well as amending our previous beliefs take dinosaurs for example 60 years ago we thought we knew everything about dinosaurs but after discovering new bonds

You just proved my point for me. You say we're "discovering new things" and "amending beliefs"—that means we didn't actually *know* anything before, we just thought we did. The dinosaur example backfires on you. We were completely wrong about them for decades, confidently teaching garbage as fact. How do you know what we believe *now* isn't equally wrong? Maybe in 60 years they'll laugh at our current dinosaur theories the same way we laugh at old ones. You're describing constant correction, not knowledge. That's the opposite of certainty.

That's what im arguing no we can't know anything for certain because certainty is subjective, belief is subjective everything is subjective

Wrong move. You just admitted we *can't know anything for certain*—that's actually my position, not yours. You opened by saying we discover things and amend beliefs, implying we're getting closer to truth. Now you're flipping to "everything is subjective." Pick a lane. But here's the real problem: if everything is subjective, then your claim "we can't know anything for certain" is also just your subjective opinion. It has no more weight than mine. You've destroyed your own argument. You can't use subjectivity as proof that certainty doesn't exist—that only works if objective reality vanishes entirely. And you know that's nonsense.
