Some people think the world looks too designed, complex, etc, for there not to be a higher force.
Meh, that's their choice.
Even if I were an evolutionist, which I'm not, I'd wonder if the evidence for evolution was all in my head, that I think too much, and that I should just believe in God.
How can you think too much? Surely the more you think the better, since you're more likely to learn?
Creatures do look designed and are complex, there's no doubt about it.
They
look designed and complex, to a degree, I'll give you that.
Many people use the eye as evidence for creation, but I'd just as easily point to the beating heart.
Both of which have demonstrable evolutionary pathways.
Any way, there's other reasons people believe in Creationism. I also think its better to believe in God, even if just so people may behave more nicely from the thought there's a God and we are here for a reason. It's a nice thought to live by.
Perhaps, but it suffers from three great flaws.
First, believing something because it's nice doesn't mean it's true, and I for one only want to believe the truth, whatever that truth may be.
Second, it presupposes that people can only behave nicely if they believe in God - it doesn't take an idiot to realise that theists are capable of atrocious acts against their fellow man, and the more fervent the belief, the more abominable the crimes they'll commit. Conversely, atheists are not inherently evil people (despite what the Religious Right would have you believe).
Third, it doesn't actually bolster the argument for Creationism. Belief in God does not require a belief in Creationism. There are theists who quite happily accept scientific theories, including the theory of common descent; they see no challange to their religious faith and the conclusions of science. The fact that we share a common ancestor with the other Great Apes, and indeed everything else on Earth, doesn't mean God doesn't exist, or that he doesn't play a role in our lives. To the theist,
that he created is more important than
how he created.
