Wouldn't that be what the false signs are for pulling fire down from heaven etc

Except YHWH is going to put fire from heaven too so I can't be sure. 

Acts 2:19 
19 I will show wonders in the heavens above and signs on the earth below, blood and fire and billows of smoke.

so how would someone know if it's truly jesus or not? I'm sure there's a question you could ask that the antichrist wouldn't want to give a fake answer to because of his pride or ego

The Antichrist is a man who appears with power on Earth and has the establishments of men immediately behind him.

Jesus Christ returns in the clouds with a great shout

Will the antichrist be an Anunnaki?
