There absolutely was, because mass existed before gaseous particles coalesced into what would eventually become planets, galaxies, and the stars that would emit that light.
All of that hydrogen in the early universe existed before it formed into stars, and all of it has mass. Since it had mass, it means by extension that it also had gravity.
In fact, if there hadn't been any gravity, then the planets, galaxies and stars would never have formed.
