Infinity. The infinite universe

Today I want to talk about the concept of  "infinity" about space and time.
 
I don't know if some time you have ever thought about time as a rectilinear line:
 
 
<---------------------------------------------------------------------------------->
       Past                                      Present                                    Future

It is said that time is infinite. It is pretty easy to think about the infinity of the future but if we think about the infinity of the past it becomes complicated.
 
If the time is infinite it means that it has always existed. Always... thousands of million of million of million of million of million... of million years lol and more millions without stopping. Time always exists, it always has been. The notion of infinite doesn't fit in human mind.
 
 
The same happens about the space...never mind if there is matter or not... the void of the space has always existed and will exist forever, indefinitely.
 
It should be an incredible spectacle. Isn't it? When the universe just was void and the time went by. Lost pulses in the space. At least, without anyone contemplating it.
 
Faithful people will say... the time and the space were created by God, but God should be somewhere before. Isn't it? Maybe in another dimension... it is possible that if God was in another dimension, God created this dimension (in this case time and space are not infinite relating with the past, they have their start and who knows if also will have an end if the Creator eliminates this dimension) but if God was in another dimension. Has been this God dimension eternal (infinite time and space)?
 
Believers defend the God existence and they say that God is perfect and infinite (there are other magnificent qualities like omnipresence and omnipotence) but if God have always existed...God have always been (Sorry that's the moment when I get into a loop and I can't see the exit)
 
So the space is infinite (however there are new theories defending that the space withdraws and if you go through one end you will appear at the opposite end). Let's suppose we defend that the universe is like a box, obviously the box is finite surely this box is into somewhere. Isn't it? There is more space. Although we could close more and more boxes, greater and greater ones of universe they will be into bigger spaces. So the space is no finite.
 
 
 
I want to mention my first post where I said: Has inorganic matter always existed? Never mind if it was all united before Big Bang (who believes in this theory) if all was void... Where does that matter come from? Is it finite? (Scientists defend that inorganic matter is finite (just the matter that exploded at Big Bang is the existent matter in the universe) I don't think so, if the space is infinite there can be thousands of Big Bangs in other far places of the Universe (so far places at millions of millions of trillion and more millions kilometers of here)
 
As I always say...there are infinite possibilities into the infinity. All fits into the infinity. This thought causes me a lot of doubts (life out the Earth, repetition of lives, unknown matter, unknown laws of physics,...)
 
We just can see the edge of universe, the cosmic edge (this edge belongs to 14.000 million years) it doesn't mean that there is nothing after this edge (On the contrary! Of course there are more) but the light that was originated at Big Bang is going over the space and until now it just can travel up to there.
