Christianity 101 for Fun Facts:
John 8:58 - Jesus is talking about the Spirit.
"I tell you the truth," Jesus answered, "before Abraham was born, I am!"
- the Spirit is eternal. Yours, mine, Jesus'
"He replied, "I saw Satan fall like lightning from heaven."
- nothing to do with Jesus.
Why did you think that these passages had anything to do with Jesus being "God", when they clearly have no bearing at all.
