In casual texts, I think so, probably, yeah, or I’d say so sound natural. Evidence-based phrases like as far as I can tell, based on what we know, or from what I’ve seen work well when your guess comes from facts or clues. For stronger certainty, choose almost certainly or highly likely. When your confidence is lower, use maybe, possibly, or it could happen.
