any life form is about passing on genetic material to next generation through reproduction. With that comes a need to firstly survive.
all the civilisation, culture, communication etc that would be needed to develop scientific discovery and engineering to warp through worm holes ( or whatever your theory is) only takes precedent once those basic needs can be net
People take risks that could/ do result in death all the time, notably in the name of exploration. Humans do not always put their own survival above other drivers.
If Humans put survival first then why would anyone become an astronaut? What's the point? It's risky and doesn't meet any of our basic needs.
At a species level, sure, survival is paramount but I doubt an entire species would travel across the universe at once.
