Agnostics tend to be lazy about expending time for searching hard/difficult truths. They dwell in the doubt, without searching for an answer to the ultimate questions of existence. They even think that it is impossible, so why bother about it.
Our curiosity to explore and know everything (omniscient) doesn't have a easy end. Maybe we need infinity time to find an answer to all the unknown (completely unknown), specially to get all important knowledge about All that exists, but it is worth it.
