“Haven’t you read,” he replied, “that at the beginning the Creator ‘made them [humans] male and female,’...” (Matt 19:4)
Of course I believe what He said. Don’t misunderstand, I am a Creationist, I just don’t know exactly how long “The Beginning” was and whether or not there may have been a gap between Genesis 1 and 2. I don’t believe in macroevolution and would stand with a God-glorifying young-earth creationist against a man-glorifying evolutionist any day of the week :)
There is no gap because Genesis 1:1 is not, itself, an act of creation. It is simply God introducing himself as the creator of all things. That's all.
I think if you'll reconsider your position, you'll see that you only believe what Christ said in the context of what man says is permissable and that is a dangerous place to be.
It was not until man said the earth and the universe were billions of years old, that 'believers' started compromising with the position you hold. If you will actually study the supposed 'evidence' for long ages, you will find that it ultimately rests on unobservable *assumptions* that are not demonstrated. As such, you should not take the assumptions of man over the clear teaching of the Word of God.
