Wow I'm catholic so I do believe in god but these reasons behind it are horribly wrong. Like the second one just cause you can concieve of something deosn't make it true I can concieve of the easter bunny but it's not real. Almost all the reasons have logical flaws. Like the third one only god can make things complex, have you even thought of cell phones or microwaves or 100 other things that are complex man has made. If you want to convince people god exists don't use such lame examples.
