crazy Bible

 "The Bible says crazy sh!t too, but nobody takes it seriously": Bill Maher

If he's talking about the Mosaic Covenant, and its requirements, then it needs to be kept in mind that it applied to the theocracy of Israel only, setting them apart from the nations, but it contained timeless morality. Things like the animal sacrifices were to teach that sin has a consequence before God, which is death; they provided a temporal kind of forgiveness for the Hebrews in their special status with God (by which the nations could observe and learn about God's holiness and salvation from sin), and they foreshadowed the future sacrifice/ death of Christ as God's ultimate answer to the sin problem of mankind (by His death we have forgiveness of sin, are justified and born again/ receive eternal life).

If he's referring to the miraculous things God did, it should be pointed out that if God created all things, then He can do anything with His creation that is not contrary to His nature.

If he's referring to what man has done to one another, it should be pointed out that man has a measure of free will and an evil nature, and God allows that free will and evil to a certain extent.

God instituted government to exercise justice on certain evil, but if the government becomes evil and does not execute justice, then that government and society's existence is limited. We see this several times in the Scriptures, with the destruction of Noah's world, the cities of the Plain (such as Sodom), the Amorites/ Canaanites, Israel (taken captive by Assyria and Babylon), Assyria, Babylon, and so on.
