How long with existing technology would it take to travel 12 light-years away from earth:
Based on the search results, we can estimate the time it would take to travel 12 light-years away from Earth using existing technology.

Voyager 1, the fastest human-made object, has a speed of 17.26 km/s. To calculate the time it would take to travel 12 light-years at this speed:
Convert light-years to kilometers: 12 light-years × 9.461 × 10^12 km/light-year ≈ 1.13 × 10^14 km
Calculate the time: time = distance / speed ≈ 1.13 × 10^14 km / 17.26 km/s ≈ 65,300 years

The Parker Solar Probe, a spacecraft designed for solar exploration, has a top speed of approximately 192 km/s (0.045c). To calculate the time it would take to travel 12 light-years at this speed:
Convert light-years to kilometers: 12 light-years × 9.461 × 10^12 km/light-year ≈ 1.13 × 10^14 km Calculate the time: time = distance / speed ≈ 1.13 × 10^14 km / 192 km/s ≈ 5,900 years

Another estimate based on the fastest spacecraft ever built (Solar Probe Plus) with a speed of 724,000 km/h (0.002c) would take approximately 59,627 years to travel 40 light-years (not 12, but provides an upper bound).

A general estimate from brainly.com and other sources suggests that with current technology, it would take approximately 1,547 years to travel 1 light-year. Scaling this up to 12 light-years:
Time = 12 × 1,547 years ≈ 18,564 years
------------------------------------------------------------------------------------------------------
Conclusion
Based on existing technology, the estimated time it would take to travel 12 light-years away from Earth varies between approximately 5,900 years (Parker Solar Probe-like speed) and 65,300 years (Voyager 1-like speed). A more general estimate based on current technology suggests it would take around 18,564 years to travel 12 light-years.
These calculations highlight the significant challenges and limitations of interstellar travel with our current technology.

Unless time really slows for human life in space, it would take a lot of slowing of that process down for any human to arrive alive with our current technology.
That's why I do not believe we are being visited by aliens from other planets. p> At best it may be heavenly spirits, is my thinking. 🙂👍
Right now I would say demons more often than heavenly spirits. 🙁
Articles like this emphasis the greatness of God. This is not something that banged into existence. And I agree with you about the devil, “the prince of the power of this air”.
