Then God said, "Let the land produce vegetation: seed-bearing plants and trees on the land that bear fruit with seed in it, according to their various kinds." And it was so. The land produced vegetation: plants bearing seed according to their kinds and trees bearing fruit with seed in it according to their kinds. And God saw that it was good. And there was evening, and there was morning—the third day.
Genesis 1: 11-13
Here we see God creating these beautiful plants. The flowers really show that God has to have created them and that something so beautiful couldn't have simply evolved from elements. Someone greater has to have shaped them with His hands for them to be so perfect!
