Can anybody can answer me what's the origin of everything? We human beings are from the earth, and the earth is from the space .....Where is the space from?.....And where is the next thing bigger than space from?

ALL things come from God. ALL of science is based on what scientists have discovered about his Divine essence. The cataclysmic and holy explosion that we euphemistically call the Big Bang was merely a rapid expulsion of Divine Methane.

From Didge's Gospel we learn:
1:1 In the beginning before all things were created, was a Being who inhabited the All-There-Is; and his name was Aye, for he was One.

1:2 Aye was an Epicurean, nay, he was THE Epicurean, and his larder was a cornucopia of culinary delights.

1:3 And Aye feasted.

1:4 Without pausing for sleep or rest he ate continuously for six days and six nights, and then he was filled.

1:5 And on the evening of the sixth day he was no longer able to retain all
that he had consumed and a mighty explosion occurred.

1:6 The stars were born, and the planets, and all that there is, and they sped from him at enormous speeds, forming constellations in the firmament.

1:7 And Aye collapsed in intoxicated slumber and lo, it was the seventh day.

So you see, science and religion are wholly compatible.

God is the Creator of space

Many people can present their own answers, but no one really knows. In the end, people tend to go with what they feel comfortable with.

There are a number of theories.  Didge explains one major theory (atheism) with his characteristic wit.

Aux Arcs states the diametrically opposed theory to which I personally ascribe.

The Z stats the reality of being human:  "people tend to go with what they feel comfortable with."

Personally, I go for the Abrahamic God concept.

I would add however that as a "cradle" Catholic, the beliefs and theories of Catholicism about reality presented themselves to me when I was in my late twenties and early thirties as, at best, incredibly inconvenient standards.

Understandably, I then spent a great deal of time and effort trying to prove that those standards were based on faulty logic and a total lack of psychological insight.

Unfortunately (or so it seemed at the time) after about 5 years of evaluating the issue, I came to the inescapable conclusion that those standards were logical in substance and wrong only in that they were occasionally misapplied.

What has followed for me over the last thirty plus years is a wonderfully open-ended, constantly surprising, and extremely rewarding personal relationship with the God who created me.

Of course, I am forced to concede that this is simply the explanation of reality that I am comfortable with.

On the other hand, doesn't it sound like a really good thing to be comfortable with?

That knowledge is "Currently" beyond what technology is capable of revealing. We may never reach this level before our time for our species runs out. Not knowing, in no way leaves the door open to man made fictional concepts merely created to "Fill in the Gaps" of our primitive knowledge. We only know WHAT we know.
