I find that most people who ask these kinds of questions do so only to prove He doesn't exist. Not that you're trying to do that. He can be seen EVERYWHERE and in EVERYTHING but people choose to dismiss Him. God gave proof in His word through prophecy, but it's all chalked up to coincidence or some other lame excuse...
Psalms 14:1 (KJV)
To the chief Musician, [A Psalm] of David. The fool hath said in his heart, [There is] no God. They are corrupt, they have done abominable works, [there is] none that doeth good.
