The TrinityGod The FatherThis is the first part of the Trinity. God is the creator of the world, the Trinity, and of you. He is the creator of everything that you can ever imagine, even Satan. (
The Story of Satan: Lucifer the Fallen Angel)
Jesus The SonJesus is God's son. God sent his son, as a man, to die for you. He is the only person who lived to DIE. He saved you from your sins.
The Holy SpiritWhen you are saved, The Holy Spirit is what comes inside your heart to fill in the gap that could not be filled by anything else, no matter what you try to stuff inside.

All of these are three different things, but they are one at the same time. God can take these three forms as he wishes, but he is them all at the same time as well...
