Its very very contradictionary to believe both. Either people are missinfomared or they really just dont know the bible or evolution. Ill throw out a few quotes. There are about 30 different ones which i have spare though.
The Bible says that man was created as a special being—in the image of God, as opposed to the evolutionary view that has man is just another animal in the evolutionary process. (Genesis 1:26-27, 2:7)
The Bible teaches that God created man by fiat, that is, by supernatural power, not by natural processes. (Genesis 2:7; Psalm 33:6,9; Psalm 148:5; 2 Corinthians 4:6; Hebrews 11:3)
The theory of evolution itself has continually changed over time. This is in contrast to biblical creationism, which has not changed over time.
Creationism and evolutionism begin from two radically different points. Creation: In the beginning there was God. Evolution: In the beginning there was a incident by chance.
And this is from some random faith website so consider most things to be bias. There are clear contradictions that people couldnt possibly believe in both.
