The skit presents us with an opportunity for discussion. Is time travel scientifically or theologically possible?
Some theological camps believe in the concepts of Foreknowledge (knowing what will happen in the future) and Predestination (exercising sovereign control over said events). Other theological camps hold to Foreknowledge but deny Predestination, asserting that God grants Man an unfettered will ("free will"), and God does not interfere in Man's exercise of that will. Still others would deny that God can even have perfect Foreknowledge of future events, because He cannot know the free will choices of Men until those choices are actually made.
Now throw into that mix the idea of time travel, specifically time travel into the past. Past events can be known (Foreknowledge) by our time traveller. Does our theoretical, theological time traveller have an unfettered will, or are future events (from the traveller's perspective) Predestined to come about regardless of the time traveller's actions? Could he or she, say, travel back to the events preceeding Exodus and assassinate Pharoah before all Ten Plagues are finished? Could he or she chop down the Burning Bush? Dump water on Gideon's fleece? Grab the coin out of the water, before the fish could swallow it (Matthew 17:27)? Could the time traveller have any impact on those events at all? God knows the number of hairs on our head (Luke 12:7) and when each sparrow falls (Matthew 10:29). The Apocryphal book Sirach says that even the grains of sand on the beach are numbered (Sirach 1:2, see also Psalm 139:18). To what extent are these things set in stone? Might that prevent a time traveller from even displacing the atoms in the air around him upon his arrival in the past?
I'm not asking that we debate the concepts of Foreknowledge and Predestination. Rather, I want to have a little fun by seeing how one's Soteriology plays out when confronted with Star Trek physics. There are no right or wrong answers here - only the opportunity to have some fun with smashing theology into technobabble.
