I'll posit a whimsical thought experiment, to get at the nature of "believe":
A silent benefactor offers to put a million dollars of his own money in trust, with accruing interest, payable to your great-to-the-nth offspring, on the condition that you bet the entire amount on whether at least some sightings of UFOS are bona fide alien intelligence.
Even though we have no answer now, it's not implausible that, in 500 years, the question will be resolved effectively conclusively:
1] We examine a downed UFO and find an alien
or
2] Our surveillance has gotten so sophisticated that 100% of all sightings come back as explained (not explainable, but are actually explained). This zero false account occurs for millions of sightings, over enough years that they get bored and reach a solid conclusion.
Assume the contract specifies whatever reasonable conditions you feel you need, within the spirit of the deal.
So, your great-to-the-nth grand-children will receive untold wealth if you bet correctly. It costs you nothing. But you're a betting man, and you can't resist a bet. Especially with someone else's money.
Which way do you bet?
Note: Intercepting the usual "I wouldn't bet because X reason or Y reason". If you don't want to humour the conceit of the thought experiment, no need to flaunt your cunning.
2. By then I estimate that our ability to gather, compare, and analyze information via networked machines will have reached a peak capable of actually fulfilling those conditions.
