Almost 6000 years ago God told Adam and Eve in the garden of Eden not to eat of that one tree of the knowledge of good and evil since they would surley die if they ate of that tree. And Adam and Eve ate of it ! Someone tricked them to test the Word of God as if God perhaps was a goof or just joking about it. And almost 1000 years later Adam and Eve did die !
"So the LORD God said to the serpent: 'Because you have done this, you are cursed more than all cattle and more than every beast of the field; on your belly you shall go, and you shall eat dust all the days of your life. And I will put enmity between you and the woman, and between your seed and her Seed; He shall bruise your head, and you shall bruise His heel.'" - Genesis 3:14-15
So the serpent got a seed ! One of the characteristic of reptiles is that they never stop growing and with time they can reach huge proportions. And Canaan which God eventually gave to the descendants of Abraham Isaac and Israel was infested with them. How big must one be to make men feel as grasshoppers ? In the book of Amos they are as tall as cedars and the Lebanon Cedar can grow to about 130 feet which would certainly dwarf 6 feet tall men. So God did not help the Israelites to conquer Canaan and kill humans ! No God destroyed the seed of the serpent offspring of fallen angels huge human angelic hybrids. And as you know every culture got a tradition about giants because once there were giants on the earth as the Bible says.
"And they gave the children of Israel a bad report of the land which they had spied out, saying, 'The land through which we have gone as spies is a land that devours its inhabitants, and all the people whom we saw in it are men of great stature. There we saw the Nephilim (the descendants of Anak came from the Nephilim); and we were like grasshoppers in our own sight, and so we were in their sight.'" - Numbers 13:32-33
"'Yet it was I who destroyed the Amorite before them, whose height was like the height of the cedars, and he was as strong as the oaks; yet I destroyed his fruit above and his roots beneath.'" - Amos 2:9
The Bible also says that the devil is the ruler of kingdoms. So when you wonder why here is so much chaos confusion crime and corruption in our world then there is a reason for this and the reason according to the Bible is because the devil and his host of fallen angels are the head of governments now heading towards a one world government.
"Then the devil, taking Him up on a high mountain, showed Him all the kingdoms of the world in a moment of time. And the devil said to Him, 'All this authority I will give You, and their glory; for this has been delivered to me, and I give it to whomever I wish. Therefore, if You will worship before me, all will be Yours.' And Jesus answered and said to him, 'Get behind Me, Satan! For it is written, 'You shall worship the LORD your God, and Him only you shall serve.'" - Luke 4:5-8
There will come a time according to the Bible when the devil and his angels are cast down to the earth so knowing this how would the great deceiver prepare the population for such an event ? Would he pretend that he and his angels are our high tech space siblings ? The ancient astronauts who have been here before who built our old civilisations ?
"And war broke out in heaven: Michael and his angels fought with the dragon; and the dragon and his angels fought, but they did not prevail, nor was a place found for them in heaven any longer. So the great dragon was cast out, that serpent of old, called the Devil and Satan, who deceives the whole world; he was cast to the earth, and his angels were cast out with him. Then I heard a loud voice saying in heaven, 'Now salvation, and strength, and the kingdom of our God, and the power of His Christ have come, for the accuser of our brethren, who accused them before our God day and night, has been cast down.'" - Revelation 12:7-9
The devil has been deceiving the world for almost 6000 years but his game of deception is about to come to a close. We all got the knowledge of good and evil and are free to be on team devil and evil or team God and good and anyway there will be a reckoning in the end.
"For God so loved the world that He gave His only begotten Son, that whoever believes in Him should not perish but have everlasting life." - John 3:16
