the humanoid form is an optimal one.
it is said that in our galaxy there are humanioids with avian reptillian canine and insect origins.
aliens ARE in the bible.
Genesis 6:1-7
"1 When men began to increase in number on the earth and daughters were born to them, 2 the sons of God saw that the daughters of men were beautiful, and they married any of them they chose. 3 Then the LORD said, "My Spirit will not contend with man forever, for he is mortal ; his days will be a hundred and twenty years." 4 The Nephilim were on the earth in those days—and also afterward—when the sons of God went to the daughters of men and had children by them. They were the heroes of old, men of renown."

numbers 13:33
"We saw the Nephilim there (the descendants of Anak come from the Nephilim). We seemed like grasshoppers in our own eyes, and we looked the same to them."
then if you replace the word angel with alien, the bible paints a very different story. that story matches the other ancient texts from around the world.
you begin to notice that the bible has stories of interplanetary wars and genetic engineering.
hebrews 13:2
"Do not forget to entertain strangers, for by so doing some people have entertained angels without knowing it."

Exodus 40:34 "Then a cloud covered the tent of the congregation, and the glory of the Lord filled the tabernacle. 35 And Moses was not able to enter into the tent of the congregation, because the cloud abode thereon, and the glory of the Lord filled the tabernacle.. 36 And when the cloud was taken up from over the tabernacle, the children of Israel went onward in all their journeys: 37 But if the cloud were not taken up, then they journeyed not till the day that it was taken up. 38 For the cloud of the Lord was upon the tabernacle by day, and fire was on it by night, in the sight of all the house of Israel, throughout all their journeys."
