Yes, definitely. But from a certain point of view, almost nothing is unambiguously true, right? You have to set a bar, and accept anything below that bar as a fundamental assumption that you take on faith. And if your bar is so low that other people might not be conscious, then you know, maybe nothing is real. You definitely can't believe in the existence of anything you haven't seen with your own eyes. I know nobody here actually believes in p-zombies, I'm just making a point in response to the original comment that it's totally reasonable to be sure that other humans are conscious, and not sure that animals are. Those positions are consistent if you're operating with a usable definition of evidence and truth. It's philosophically possible that other people are zombies, but it's practically possible that some animals are zombies.
