But anything else would be supernatural. And Secular Humainism can't accept the supernatural into its philosophy.
What jar is saying is that the conditions at the Big Bang are so vastly different from present conditions that what we call matter might be incapable of existing. However the existent entities under those conditions would still be physical.
Take for instance a proton, something which is a fundamental component of any atom. A proton is actually a low-energy/temperature phenomena and not a universal particle.
Turn up the energy/temperature and it dissolves, not because it melts or anything, but because the physics required for it to exist only occurs at low temperatures/energies. At high energies a proton can't occur.
Similarly, back at the Big Bang things might have been so hot/energetic that no particle that we know could occur as a phenomena.
In addition to this fact even the word particle itself begins to lose meaning when space-time becomes very curved, such as near the Big Bang.
These are very subtle issues and to be fair require a good deal of familiarity with the subject, as they involve two very difficult fields called "non-perturbative QFT" and "QFT in curved spacetimes" and ultimately a much more difficult subject called "Quantum Gravity".

So why do so many "scientists" (and interestingly enough the word science means knowledge) find it hard to "acknowledge" that if there is a singularity, then maybe it had a cause to be there, and since the law of causialty is factual, then maybe, just maybe, "In the beginning God said; Let there be light..."
The rest of your post contains elements of appreciation of God's work as you see it in science. Which is fine as it is personal opinion.
However, as for the section quoted above, the main reason no scientist would say this is because it would be a massive cop-out when it comes to explaining the mechanisms of the singularity.
Here we have an entity where General Relativity gives over to some other physical domain and our job is to find out the rules of this new domain. Adopting a "God did it" attitude, in a process sense, won't get us anywhere.
N.B. As has been said before on this thread, you shouldn't view the universe as being created at any particular point on its own surface such as the Big Bang.
