A few random notes:

Angel is a terrible English word. It's a job title, not a typological name. It is basically "one who bears a message from The Most High." 

There are gods, little G gods. They were given dominion over parts of the earth. 

Nephilim (children of the gods who misapproprated worship to themselves and came to earth for the purpose of taking human wives) have been heavily associated with red hair and paler skin. 

All of the various pantheons of gods that pagans worship are either the Watchers (the group that came down I mentioned above) or others that were corrupted by the draw of power through the worship of humans later (see Psalm 82,IIRC). 

Humanity shares a very common past. The similarities of "myths" are shocking and point to this. 

I believe that the Biblical account is the true account of things.
