. The main difference between God’s judgements of Lucifer’s world and Noah’s world is that Lucifer’s world was completely destroyed. All life on earth in Lucifer’s world totally perished. This was not the case resulting from God’s judgement of Noah’s world. God did not completely destroy all of Noah’s world. All life on earth did not totally perish, as in the case of Lucifer’s world. Of course, in both of these judgements of God, Satan and his fallen angels could not perish because God created them as immortal spirit beings. Finally, let us now consider some relevant scientific theories, which complete our study of the Pre-Adamic Age. The K-T extinction event Many scientists now believe in a theory proposed in 1980 by the physicist Luis Alvarez and his son Walter Alvarez, a geologist. Their theory says that a mass extinction of plant and animal species occurred as a result of a huge asteroid impacting the earth's surface at the end of the Cretaceous period, sixty-five million years ago. This is known as the K-T extinction event. The following quote summaries the general scientific belief about this K-T extinction event. 'In the Alvarezes' scenario, an asteroid 10 kilometers in diameter struck the earth at high velocity, forming a crater 150 kilometers wide. In addition to the immediate devastation of tidal waves, global fires, and giant storms, impact debris hurled into the atmosphere at high altitude spread around the Earth,preventing sunlight from reaching the ground. With photosynthesis blocked, herbivorous and carnivorous species died as the food chain was snapped at its base.' It is interesting, yet not surprising, that this scientific theory supports the Bible's account of God's global tohuw and bohuw judgement in the Pre-Adamic World. We know from Scripture that God's global tohuw and bohuw judgement involves the powers of the heavens being shaken, stars (asteroids) falling on earth and sunlight being withheld or blocked from reaching the earth’s surface. Do you know that the Bible is amazingly clear that the earth will be struck by an asteroid once again in the future tohuw and bohuw judgement, at the Second Coming of Jesus Christ? Revelation 9:1-21 Then the fifth angel sounded: And I saw a star (asteroid) fallen from heaven to the earth. To him (the angel) was given the key to the bottomless pit. 2 And he opened the bottomless pit, and smoke arose out of the pit like the smoke of a great furnace. So the sun and the air were darkened because of the smoke of the pit. Uniformitarianism Scientists worldwide are increasingly beginning to realise that they must include catastrophic events in their philosophy of uniformitarianism. This is a scientific theory, which says that geological processes operating at present are the same processes that operated in the past, and that there have been no catastrophic events in earth's history. Uniformitarianism is commonly described as 'the present is the key to the past'. Scientists are now beginning to accept that geological evidence shows that catastrophic events occurred in earth's history and 'the present is not always the key to the past'. Obviously, uniformitarianism has played a part in the shaping of earth's geology, as the earth is millions of years old. However, it is clear that earth's geology has also been greatly impacted by God's global cataclysmic tohuw and bohuw judgement of Genesis 1:2. We believe that Christians who are knowledgeable geological scientists, and who understand and accept the truth of the Pre-Adamic world, which lasted many millions of years, are in the best position to correctly understand earth's geology. The ‘Big Bang’ theory The Big Bang theory, which teaches that the universe began with an explosion of a primeval atom, is unbiblical and nonsensical. How can the vast universe, with billions of galaxies and stars and our beautiful planet earth with its amazingly complex and intricate design and life, come from an explosion of one tiny atom? Where would this primeval atom have originated in the first place? The truth of the Bible that God created the universe and the earth in the beginning instantaneously, many millions of years ago, makes a lot more sense than the Big Bang theory. The theory of Evolution God is the Creator of all things. He commands and things happen. There is not a hint anywhere in the Bible that God used evolution to create life. As we reject Young Earth Creationism, we also reject the theory of Evolution. Conclusion We appreciate that Young Earth Creationists are passionate in their belief that the Bible is the infallible Word of God, God is the Creator and Evolution is a false theory. However, the sad irony is that YEC itself, with its false interpretation of the creation account in Genesis and belief in a young earth, supplies evolutionists and atheists with all the ammunition they need to ridicule the Bible as contradictory, illogical and scientifically nonsensical. Young Earth Creationism has yet to discover the biblically correct 'Answers in Genesis', answers that are not only very logical, but also, scientifically and geologically defensible, answers that not only protect, but also, enhance the credibility of the Bible as the true Word of God. The correct biblical understanding of the Genesis account of creation and acknowledgement of the Pre-Adamic World is the best and the only way to fight the false theories of The Big Bang and Evolution taught in our schools and universities today.
