Not in the literal sense—not with what we currently know.
Humans cannot live forever because our bodies are biological systems that naturally wear out over time. Aging leads to cell damage, weakened organs, and eventually death.
However, science is exploring ways to extend human life significantly, such as:
Anti-aging research (slowing cell aging)
Regenerative medicine (repairing organs and tissues)
Genetic research (targeting age-related diseases)
Artificial organs and biotechnology
But even if lifespan increases, true immortality (never dying at all) is still not scientifically possible or proven.
So for now, the reality is:
We may be able to live longer and healthier—but not forever.
A deeper question to think about:
If humans could live forever, would life still feel meaningful?
