Yup, well you can travel back in time as far back as you can imagine and never find that limit, never find the ultimate truth.
All the haughty god-like logic and science, all the theories that some humans believe are indisputable are regularly disputed and new theories are presented. Then there are some things that mere mortals can never truly know.
There is certainly no scientific consensus about the origins of all things, Michael Crichton wrote about the claims about consensus in science, "There is no such thing as consensus science. If it's consensus, it isn't science. If it's science, it isn't consensus. Period.”, “Let’s be clear: the work of science has nothing whatever to do with consensus. Consensus is the business of politics. Science, on the contrary, requires only one investigator who happens to be right, which means that he or she has results that are verifiable by reference to the real world. In science consensus is irrelevant. What is relevant is reproducible results. The greatest scientists in history are great precisely because they broke with the consensus."
If someone claims there is a scientific consensus, then you've found a charlatan, a political actor.
Where does Joe Biden fit into all this? He's a charlatan of course!
