The creation account in Genesis 1 conflicts with the order of
events that are known to science.
In Genesis 1:1, the earth and "heaven" are created together "in
the beginning," whereas according to current estimates, the earth was formed
about 9 billion years after the universe began its current expansion 13.7
billion years ago.
In Genesis, the earth is created (1:1) before
light (1:3), sun and stars (1:16), birds and whales (1:21)
before reptiles and insects (1:24), and flowering
plants (1:11) before any animals (1:20). The true order of events in each case was just the opposite.
