IF you can answer all of those questions, then their is a god.
It takes a long time to really study scripture and know everything one is talking about or reading about. Its not as simple as "answer these questions" and God exists. Some things in the Bible are meant literally and some are figuratively. We cannot even comprehend everything God does and means since he is the omni-everything. And even after all that, you can do all the reading and studying and "arguing" you want to - but what it all comes down to is quite simple actually. Either you believe Jesus Christ is the son of God, he lived a perfect life we should have lived and died for our sins, and you truly know, understand, and believe that, thus surrendering your life to him........or you don't. Its called faith.
btw nobody has answered my question jet, somebody who believes in the existance of a God, explaine to me:
If the Earth/Universe was created by a God, where did this God then come from, and could it be that he is a highly evolved Alien spiecies, and that there are more of his kind, and also why not??
That is a great question, one I use to ask and still do occasionally. The best answer I can come up with is that God is eternal - meaning he has no beginning and end. He has just always existed, so in a sense he came from "nowhere" because he has always been. If you think about it though, the question cannot even be applied to God in the first place because eternity is a term that we use to define something that has no beginning/end. But since God has no beginning or end, He has no beginning (get it?), therefore, He is outside of time, and outside of eternity. Its weird.
To answer your "highly evolved Alien species" quesion, I'm assuming that these aliens you speak of live in the universe, and not in heaven with God, no matter how much they are "more of his kind." You see, God created the universe. But before He did that, He was just existing, and time had no meaning, no relation to Him. So, time began when God created the universe.
what is it that is not correct.
Well, the thing about 1 day equal to 1,000 days. If you're referring to the quote in 2nd Peter Chapter 3 verse 8, he says "With the Lord a day is like a thousand years, and a thousand years are like a day." - The key word in there is the word "like." What I'm pretty sure he is saying is that our lives are just like a blink of an eye to God, since He lives in eternity. They are just a speck, a dot, on an infinite timeline.
My Bible has these notes about that verse: "God does now view time as humans do. He stands above time, with the result that when time is seen in the light of eternity, an age appears no longer than one short day, and a day seems no shorter than a long age. Since time is purely relative with God, he waits patiently while human beings stew with impatience."
