God's Communication With Mankind

Early in Man's history, God communicated with humans.
The Bible record describes divine conversations with Adam and Eve, Noah, Abraham, and others.
(Genesis 3:8-10;6:13,15:1)

Dreams ,voices, and visions were used to communicate God's will and to the produce the Bible.
However after the Bible was completed, was there a need for direct heavenly communication with mankind?

No, since the Bible states that the Holy Scriptures make " the man of God...fully competent, completely equipped for every good work."
(2 Timothy 3:17)

According to the Bible, guidence for theses troubled times is to come from the written Word of God.
Neverless, is there any reason to believe that we would receive communication or special instructions directly from God through an extraterrestrial spokesman?

No, for the apostle Paul stated:
" Even if we or an angel out of heaven were to declare to you as good news something beyond what we declare to you as good news, let him be accursed."
-- Galatians 1:8
