Hello, The Bible story of fallen angels and marital relations with women is just a story made-up by God, since of course the angels whether obedient or disobedient could not have made human bodies without the direct order from God to do so, Revelation 22:6-7. The story, however, is an example of sin even in the spirit realm of angels close to the presence of God, boldness if you well, Psalms 109:1-20.
It looks surprising but humans did make Stonehenge even at an early time in human history, the ability to crave pictures into stone was a skill that humans possess, Genesis 4:17-22. They are just rocks it probably took a long time to chisel out, but a sculptor may have created it.
