"Remember the sabbath day, to keep it holy. Six days shalt thou labour, and do all thy work: But the seventh day is the sabbath of the LORD thy God: in it thou shalt not do any work, thou, nor thy son, nor thy daughter, thy manservant, nor thy maidservant, nor thy cattle, nor thy stranger that is within thy gates: For in six days the LORD made heaven and earth, the sea, and all that in them is, and rested the seventh day: wherefore the LORD blessed the sabbath day, and hallowed it."
The "Gap Theory" was invented to explain millions of supposed missing Biblical years to accomodate Darwin's 1859 book "The Origin of Species." It was a reactive explanation by Bible expositors of that day afraid of Darwin's theory being projected as scientific fact.
"And they shall turn away their ears from the truth, and shall be turned unto fables. " (2 Timothy 4:4)
Darwin's "Theory of Evolution" was invented from his misinterpretation and exposure to new found plant and animal life which God desiged with environmental adaptability within species. No species transitional fossils have ever been found. Darwinists stretched this under the guise of millions of years into an unexplainable and unprovable metamophysis of inanimate matter to life. "Intelligent Design" is the only explanation for plant/animal male/female interralational perfection and microbiological irreducible complexity and information-stored (DNA) instructional construction.
"Timothy, keep that which is committed to thy trust, avoiding profane and vain babblings, and oppositions of science falsely so called:" (1 Tim 6:20)
