Since you only observe others outwardly & superficially by their actions, not their innermost being, how is it one can think they are omniscient when it comes to what is inside of others?
Can you see a crowd of people and list the percentage of purity or rottenness in each heart? This one is 50%, that one 25%, that one 85%?
When have you ever seen another person & been able to judge that their motives are 100% pure? Are you God the Omniscient?
How much of even your own heart do you comprehend? Only what’s on the surface, the superficial?

1Though I speak with the tongues of men and of angels, and have not charity, I am become as sounding brass, or a tinkling cymbal. 2And though I have the gift of prophecy, and understand all mysteries, and all knowledge; and though I have all faith, so that I could remove mountains, and have not charity, I am nothing. 3And though I bestow all my goods to feed the poor, and though I give my body to be burned, and have not charity, it profiteth me nothing. (1 Cor.13)
And no wonder, for even Satan disguises himself as an angel of light. (2 Cor.11:4)
