Fallen angels interbreed with daughters of man Nephilim. Nephilim were the ancient men of renown … demigods of mythology, giants, etc. Fallen angels became the ancient gods of mythology, to have men worship them. Read book of Enoch concerning description of fallen angels and one (cannot remember the name) sounds exactly like the Egyptian Ra.
Lucifer and the fallen angels planned to pollute the human DNA so that the Savior (Hamaschiach) could not be born … thus God destroyed the surface of the earth with the flood. Physical bodies of fallen angels and nephalim were destroyed, but spirits were not.
For thousands of years, they have been interfering with and misleading men, planting false artifacts and distorting history, and manifesting in the physical world as demons (or aliens). Most are trapped or exiled in another (spiritual) dimension - but may be amassing toward earth in the form of "aliens."
At some point in time very soon, they will be unleashed by Lucifer on all of the earth. Antichrist will rise to power over a large part of the world, if not the whole world. You will know him by the 7-year "peace" treaty he brokers between Israel & muslim world.
We are all born with an immortal soul. You will spend all of eternity somewhere, after your life here on this planet expires.
There will be Heaven for those who choose it, and the lake of fire for everyone else. All have been/will be given the opportunity to choose salvation - by the narrow path - through our Lord and Savior Yeshua Hamaschiach.
The only time that it is too late to be saved is if you die before accepting Him, or if you accept the Mark of the Beast. To be saved, you must confess with your mouth and believe in your heart that He is who He said He was, that you are not able to live a perfect sinless life under your own power, that you need and accept His free gift of Grace (salvation) to pay the "fine" for your sins, and that you believe (in your heart) that He has saved you.
