Is Jesus really the Father?

The theory you proposed is false because it contradicts the Scripture's teaching concerning the Godhead and the Son of Man, Jesus Christ. The clear testimony of Scripture is that Jesus Christ was the Son of God (not the Father Himself) and He was sent by the Father to die for the sins of men. Before doubting the truth of the trinity, we must remember the words of Scripture concerning those who deny the three Persons of the Godhead:
 

Luke 10:16 “ The one who listens to you listens to Me, and the one who rejects you rejects Me; and he who rejects Me rejects the One who sent Me.”
 

1John 2:22 Who is the liar but the one who denies that Jesus is the Christ? This is the antichrist, the one who denies the Father and the Son.
1John 2:23 Whoever denies the Son does not have the Father; the one who confesses the Son has the Father also.
 

We also recommend you read the following explanation of the Trinity.
