I agree!
Here's a short article I found on Kent Hovind's website blog:
The Gap Theory Denies the Purpose of the Cross
Dr. Kent Hovind
October 26th, 2010
Without a doubt, the foundation upon which our salvation and hope rests is the substitutionary death of Christ on the cross. God created a perfect, sinless earth and placed upon it a perfect, sinless man. This man, Adam, enjoyed close fellowship with his Creator until he sinned and broke the perfect relationship between God and man. Ever since that time, death and degradation have plagued God’s once-perfect creation, and man has been separated from God. However, the shedding of Christ’s innocent blood on the cross can restore man’s fellowship with God and provide him eternal life. Through Adam’s sin, death entered into the world; but through Christ’s sacrifice, salvation is made possible (Romans 5:19). Therein lies the gap theory’s greatest error, the placement of sin and death prior to the existence of Adam. If death existed prior to Adam’s sin, then how could it be the result of sin?

Romans 5:12 Wherefore, as by one man sin entered into the world, and death by sin; and so death passed upon all men, for that all have sinned:
Were the plants and animals just by-products or do they sin also?
