Answer:

The concept of achieving immortality has been a subject of fascination and speculation for centuries. While it is impossible to predict the future with certainty, there are several reasons why achieving literal immortality for humans is currently considered unlikely:

1. Biological limitations: The human body is subject to wear and tear over time, leading to aging and eventual death. Even if we could address specific causes of aging, it is uncertain whether we could completely halt or reverse the process indefinitely.

2. Complexity of human biology: Humans are complex organisms with intricate biological systems that are susceptible to a wide range of diseases, genetic mutations, and cellular damage. Overcoming these challenges would require a deep understanding of the intricacies of human biology, which is still an ongoing area of scientific research.

3. Ethical considerations: Immortality could have profound implications for society, such as overpopulation, resource scarcity, and disparities in access to life-extending technologies. These concerns raise ethical questions about who would have access to immortality and its potential impact on the overall well-being of humanity.

However, it's worth noting that while literal immortality may be beyond our reach, advancements in medical science and technology could significantly extend human lifespan in the future. Research into regenerative medicine, genetic engineering, and other areas may lead to breakthroughs in slowing down the aging process and mitigating age-related diseases. This could potentially result in a significant increase in human lifespan, although not necessarily immortality.

It's important to approach discussions about immortality with a balanced perspective, taking into account scientific progress, ethical considerations, and the inherent uncertainties of the future.

Explanation:

While, as shown with creatures such as hydra and Planarian worms, it is indeed possible for a creature to be biologically immortal, these are animals which are physiologically very different from humans, and it is not known if something comparable will ever be possible for humans.
