"Space giants" from a culture that had no concept of outer space? That sounds to me like some New Age silliness, or "re-interpretation" if I was being nice.
The KJV translates it "giants" and describes them as "mighty men of old". Apparently the offspring of demon-possessed men, killed in the flood. I have seen Jewish speculation that the mythology of the Greek and Roman gods were distortedly based on them, but this is not part of the Jewish religion, nor am I convinced by this. Such speculation is merely a data point.
The "Greek and Roman gods" hypothesis, if I may so dignify it, is not irrelevant. Ovid attributes the flood to Jupiter having a snit, nothing about Divine justice. It's worth reading Metamorphoses just as part of a general cultural education. The creation story is much like the Bible as well, except that creation is attributed to an unknown god. After creation and the flood, it is not even slightly similar to the Bible, but it is as much part of our cultural heritage if not of religious truth or morality.

Reading right out of the Torah in Hebrew the word is "nefilim", which means "the fallen" (from the Heavens, presumably) and is rendered as "the Titans" or "Giants" in most English translations of the Hebrew Scriptures. "Giants Fallen From the Heavens" is more-or-less the same thing as "Space Giants", isn't it?
We know that the Nefilm were halfbreeds -- the offspring of fallen angels ("the Sons of God") and human women. How exactly was this twisted mating accomplished? Nobody knows, of course, but with a bit of imagination one can speculate that perhaps it occurred through technological means, implying a society far more advanced than is usually imagined for that early period of history.
As I said: I'm no scholar. All of this is pure moonshine. Still, one must admit that there are an awful lot of funny things about the Noah story.
