John D: what you’re asking about are so-called future contingents. This is a perennial and unresolved problem in logic/epistemology ever since Aristotle talked about the sea battle that was going to take place tomorrow.
There appear to be two basic options here: 1. these propositions have a determinate truth value but it’s not known to us at the moment but is known to somebody with greater epistemological powers, e.g. God; or, 2. these propositions have no determinate truth value and so are known to no one, including God.
The argument has been going on for 2,500 years and the jury’s still out!
