Cut to the chase. Does this mean humans will never get star travel?
Does going to the sun count?
Not at all! Read the story found in the fifth chapter of Daniel, Old Testament. we just haven’t learned how to get back and forth from wherever that being stood when they reached into Belshazzar’s palace party central. And don’t forget that jesus left the burial wrappings and the stone tomb without unwrapping or rolling away the stone. He appear in a locked and shuttered room and vanished right before the eyes of two whom had walked with on the road, after he broke bread with them. Star jumping won’t be any big deal once God allows us to know how He did those things He wrote down for us in the Bible.

Not with any kind of reaction engine anyway. What we have now propels the craft forward by expelling reaction mass backward (equal and opposite). To exceed the speed of light you would need to expel mass at greater than the speed of light. I'm no rocket scientist, but I don't see how we can do that.
Guess we'll have to cheat in some sci-fi fashion, like harnessing wormholes or folding space...
“Cut to the chase. Does this mean humans will never get star travel?”
We’ll get there. We just don’t understand even the basic concepts yet.
In the most recent Star Trek movie, the elder Spock showed the younger Scotty the equation to achieve transport through hyperspace. Scotty took one look at the numbers and said, “Huh, I didn’t realize that space was the thing moving.” That’s science fiction, but it does illustrate one point: Our ideas of physics are vastly limited.
One hundred years ago the Sopwith Camel biplane was still a few years away. Think of where we’ll be in another hundred.
