what are the criteria for scientist to consider a species extinct? maybe they just didnt search enough, like given the vastness of earth there r probably areas still unexplored?

It’s an assumption. If there hasn’t been any sightings of an species in a while and previous studies have shown it’s on a downwards trend then they’ll posit it’s extinct. This is also why every now and again they’ll rediscover a declared extinct species.
