so, Where did energy emerge from? where was it hiding? imho, my answer stands:
Obviously it emerged when the BB emerged. The bone of contention is though that while we have plenty of evidence for the BB having occured, we know nothing of that first 10-43 seconds from the initial event. This is the quantum/Planck level, and our laws of physics and General Relativity, fail us at this realm.
Many cosmologists though speculate that the total positive energy is balanced by the negative energy of gravity, meaning the overall energy content of the universe might be zero, removing the need for a specific "creation" event.
(google) gravitational potential energy is considered negative because it is a "bound" or "binding" energy. In physics, gravitational potential energy is defined as zero when two objects are infinitely far apart. Because gravity is always attractive, energy must be added to pull objects apart, making the potential energy negative as they move closer.
(wiki)Negative energy in cosmology is a theoretical concept representing gravitational potential energy that offsets positive matter energy, contributing to a "zero-energy universe". Often associated with negative pressure or vacuum energy (like dark energy), it drives accelerating expansion and is sometimes referred to as negative mass, gravitational potential energy, or the dark fluid component.
Zero-Energy Universe Hypothesis: Some physicists propose that the total positive energy (matter) in the universe is perfectly balanced by the negative energy (gravity), suggesting a
"universe from nothing"... "
"The cosmological constant was first proposed by
Einstein as a mechanism to obtain a solution to the gravitational
field equation that would lead to a static universe, effectively using dark energy to balance gravity.
[14] Einstein gave the cosmological constant the symbol Λ (capital lambda). Einstein stated that the cosmological constant required that 'empty space takes the role of gravitating
negative masses that are distributed all over the interstellar space'.
[15][16]
The mechanism was an example of
fine-tuning, and it was later realized that Einstein's static universe would not be stable: local inhomogeneities would ultimately lead to either the runaway expansion or contraction of the universe. The
equilibrium is unstable: if the universe expands slightly, then the expansion releases vacuum energy, which causes yet more expansion. Likewise, a universe that contracts slightly will continue contracting. According to Einstein, "empty space" can possess its own energy. Because this energy is a property of space itself, it would not be diluted as space expands. As more space comes into existence, more of this energy-of-space would appear, thereby causing accelerated expansion.
[17] These sorts of disturbances are inevitable, due to the uneven distribution of matter throughout the universe. Further, observations made by
Edwin Hubble in 1929 showed that the universe appears to be expanding and is not static. Einstein reportedly referred to his failure to predict the idea of a dynamic universe, in contrast to a static universe, as his greatest blunder" .https://en.wikipedia.org/wiki/Dark_energy

While it seems science/cosmology is at an impasse with regards to the actual instant of the BB and the short period after, (10-43 seconds) many of our technological marvels like the HST, the JWST, the LHC, the RHIC, and LIGO, are giving us glimpses and ideas about the quantum realm.
The thing is that scientists understand the limitations at this time. The sad part is that those motivated by a supreme being as the overall creator, are quick to claim victory over science by installing that supreme being....commonly known as "the God of the gaps"
