Are there background gravitational waves from inflation and the creation of matter at the start of time?

  That's an open question and a very interesting one. Detecting them directly with a LIGO-type insrument is several orders of magnitude beyond our ability right now, but there is also the hope for indirect detection based on looking at patterns in the sky.

    Thank you for answering me. Presumably they would explain the condensation of early galaxies and stars?

      The large structures in the universe are assumed to be rooted in fluctuations that got inflated to their size. See https://en.wikipedia.org/wiki/Inflation_(cosmology) https://en.wikipedia.org/wiki/Inflation_(cosmology)
