(i apologize to the people that i've stolen) well the monsters were just an unknown human nation untill the mysterious mage/wizard curse them (it transforms them into monsters), it might be the reason why the monster declare war on humans, after the monster's defeat they were sended to mt.ebbot, the mage/wizard blocked the exit by creating a barrier, many years later the monsters forget who they are, it is also reason you see them trying to be like the modern day humans (such as talking monsters, humanoid monsters (asriel,undyne,alphys,sans, papyrus, toriel, asgore and other monsters)and their own techonologies) and why we spare them because they were humans back then.

its time to disprove this theory by yourselves guys (sorry for my english)
