Boy

Are you the Planck Era?

Because unfortunately you are hot and dense as all get out

“what was there before the Big Bang?”

As far as I can learn, the answer to this question is unknown because, to quote the above linked article [emphasis mine]:

“Planck Epoch (or Planck Era), from zero to approximately 10-43seconds (1 Planck Time):   This is the closest that current physics can get to the absolute beginning of time, and very little can be known about this period. General relativity proposes a gravitational singularity before this time (although even that may break down due to quantum effects), and it is hypothesized that the four fundamental forces (electromagnetism, weak nuclear force, strong nuclear force and gravity) all have the same strength, and are possibly even unified into one fundamental force, held together by a perfect symmetry which some have likened to a sharpened pencil standing on its point (i.e. too symmetrical to last). At this point, the universe spans a region of only 10-35 metres (1 Planck Length), and has a temperature of over 1032°C (the Planck Temperature).”

All of the above key terms have links; these would be great places for you to click to learn more about each concept.
