Science doesn’t know everything, nor does it claim to. However it is the best and most accurate method we have for understanding how the universe functions.
1.Facts are subject to change
As new information becomes available our knowledge must expand to incorporate this data. Far be it from being a weakness, this ensures what we know is accurate.
New questions are raised when attempting to answer old ones. In this way we will never “know” everything. Rather than being disappointing this gives us unlimited areas to explore.
3. Omniscience is boring
At the turn of the last century it was said all there was to know about physics had been discovered. Then Einstein and others came along and changed the game. If there were no more questions to answer the world would be a stagnant dead place.
Because there are gaps in our knowledge doesn’t mean you can insert whatever supernatural or new age crap you want. Nor does it mean you should askew learning new facts. After all were it not for science many of the things you enjoy today would not exist.
