Nor do you -- but perhaps we might consider whether or not some measure of probability -- based on real and available information -- might at least give us reason to at least posit a likely guess.
The problem is that many times, we NEVER hear the word "guess" even though it is exactly that. How many times have we been presented with a "guess" in a "fact-like" manner?
You will still "believe" in a magic creation with all kinds of intent and design and purposes of all sorts, yet you will have absolutely zero evidence for any of it..."
If you have spent any time researching the subject of origins, you have undoubtedly been presented with scientific evidence of creation - just because you refuse it doesn't suddenly invalidate it.
Now, we can also make a simple observation by doing any experiment at home -- if all the objects on a table-top are moving away from each other, and moving away faster, the farther from the centre they are, then it is really most reasonable to assume that they were all closer together a minute ago, and much closer together 10 minutes ago, and all so very much closer together an hour ago -- and so on until we can only conclude that they were all in the same place at some (calculable) time in the past.
Sure, its reasonable to assume things may have started that way, but to go so far as to say all mass was compressed into a single point (as some believers of the big bang suggest)? Since when do we see huge masses compressed into a single point? Or, as others suggest, or sued to suggest, that there was nothing in the beginning, and after the big bag, all planets and stars came from nothing? All of these "guesses" are violations of physical laws; they are NOT consistent with our observations. Of course, some will want to make "exceptions" to those physical laws to fit their various conveniences. Any such "guesses" are anything but scientific.
Now, what was before that? You got me -- I have no idea. And here's where the science-minded and the religion-minded part ways -- I'm quite comfortable saying "I don't know." Others can't live until they've got a definitive answer -- even if they have to make it up and then, as you put it believe it.
IMHO, If you were truly comfortable not knowing the answers, you would stop "guessing" and simply say "I don't know" and go no further. In this regard, you are just as religious as anyone else.
Here is some pure UNscientific garbage spewed by the "scientific' community:
“The universe is flat. It has zero total energy and it could have begun from nothing ...
If you have nothing in quantum mechanics, you'll always get something. It's that simple.”

Matthew 7:
The Narrow and Wide Gates
“Enter through the narrow gate. For wide is the gate and broad is the road that leads to destruction, and many enter through it.
14But small is the gate and narrow the road that leads to life, and only a few find it."
We will notice that Jesus did not mention the educational status of those on either road. We can have ten PhDs but if our intent is to deny God and His Lordship over us, we will be on the Broad Road running away from our Creator. And in complete darkness. And making hearty attempts to drag the rest of us down with them.
Don't let ANY human being tell you they can guess how the world began or how life began. They can't even BEGIN to guess...
