One of current time most studied subjects in science is the mystery how the Universe came in to existence.
In the past century mankind made incredible advancements in acquiring knowledge and the most important astronomical discoveries is undoubtedly the expanding of the universe..
That really was the revelation that led to the explanation how the Universe started.
Symplified it came to this :

If an object is moving in a certain direction, it is not that difficult to find the origin of this movement.
You just have to reverse the trajectory (basically view the film backwards) and you can see where it came from..
From the measured speed of the expansion it is also quite simple to calculate WHEN that happened (speed = traveled distance : time )
Of course the mathematics used to calculate the place and time of origin aren't that simple but the outcome shows that our universe originated from one single spot 13.8 billion years ago.
A torrent of scientific discoveries proved theories that thus far only existed in theoretical and physical mathematics..
The religious perception as estimated Archbishop James Ussher in 1594, that placed the creation of the universe at 4004 BC was hereby, definitely and finaly totally, refuted..
But that is a different story..
Even though the religious explanation was crumbling at it's foundations religious creationists still presume that it must have been an intelligent source (deity), which orchestrated it all ..
But instead of providing an answer, this only adds a new question: what made this intelligence come in to existence ? to assume that this intelligent designer always has existed is the religious way out, meant discourage believers to look what is behind that horizon of knowledge and creates a loop of circular reasoning that has no end, nor beginning ..
I see a new mystery that yet has to be explained, that does not need some intelligent agent in the commencing of the universe, why not assume that the universe has always been there ?
It is something that we cannot comprehend, maybe their will become a day when we can.
The comprehension of mankind has grown epically in the past 200 years.
For example think of this:
Suppose you would be able to travel back in time and find most fearless knight of the middle ages
Then transport him for 10 minutes to a 21st century I-MAX theater and show him a scene from the horror movie Hell Raiser.
Of course all in THX surround full blast and then transport him back to his own time..
This Brave knight would have experienced this as has he has witnessed HELL and was allowed to come back ..
That is the only way he can explain what happened to him..
We in our recent time have learned to comprehend things like the projecting of images on a wall ,remember that the device was called "magic Lantarn" to 3D I-MAX Movies. Now it is explainable to us because we know how it is made..
In our modern age these things are normal to us after we assimilated the knowledge for that..
Maybe someday we learn to comprehend the things we currently are not yet able to picture in our mind, because to most of us, our imagination is limited by the three dimensional world we have around us ..
