When Did “The Last Days” Start?

Some say “the last days” began some time in the twentieth century, and others say they started sometime in the twenty-first century. When did “the last days” start? What does the Bible say? “The last days” started with Christ’s first coming. How do we know this?
SCRIPTURAL EVIDENCE
Acts 2:14-17 – “Peter . . . addressed the crowd . . . ‘let me explain this to you . . . this is what was spoken by the prophet Joel: “In the last days, God says, I will pour out my Spirit on all people”‘” (NIV). Peter said the last days had begun then, fifty days after Christ’s execution, and quoted Joel’s prophecy to prove it.



Is it possible that God the Father is the only one who is Almighty, and his Son, Jesus Christ and the holy Spirit are not Almighty?
