Various forms of spontaneous generation quote
"When it comes to the origin of life on this earth, there are only two possibilities: creation or spontaneous generation (evolution). There is no third way. Spontaneous generation was disproved 100 years ago, but that leads us only to one other conclusion: that of supernatural creation. We cannot accept that on philosophical grounds (personal reasons); therefore, we choose to believe the impossible: that life arose spontaneously by chance." George Wald, winner of the 1967 Nobel Peace Prize in Science, in Lindsay, Dennis, "The Dinosaur Dilemma," Christ for the Nations, Vol. 35, No. 8, November 1982, pp. 4-5, 14. [1]
"When it comes to the origin of life, we have only two possibilities as to how life arose. One is spontaneous generation arising to evolution; the other is a supernatural creative act of God. There is no third possibility...Spontaneous generation was scientifically disproved one hundred years ago by Louis Pasteur, Spellanzani, Reddy and others. That leads us scientifically to only one possible conclusion -- that life arose as a supernatural creative act of God...I will not accept that philosophically because I do not want to believe in God. Therefore, I choose to believe in that which I know is scientifically impossible, spontaneous generation arising to evolution." - Scientific American, August, 1954.
George Wald, an evolutionist, states, "When it comes to the origin of life there are only two possibilities: creation or spontaneous generation. There is no third way. Spontaneous generation was disproved one hundred years ago, but that leads us to only one other conclusion, that of supernatural creation. We cannot accept that on philosophical grounds; therefore, we choose to believe the impossible: that life arose spontaneously by chance!" ("The Origin of Life," Scientific American, 191:48. May 1954). [2]
