Traveling to other planets?

Quite often I’m surprised at bold statements of people “with a vision” that claim in 50 years we will be living on other planets.

First, I would like my personal and religious convictions to shine through, in that the bible said that “Earth was made for men to rule over”.
Genesis 1:26-29 says the following:
26Then God said, “Let us make mankind in our image, in our likeness, so that they may rule over the fish in the sea and the birds in the sky, over the livestock and all the wild animals,a and over all the creatures that move along the ground.”
27So God created mankind in his own image, in the image of God he created them; male and female he created them.
28God blessed them and said to them, “Be fruitful and increase in number; fill the earth and subdue it. Rule over the fish in the sea and the birds in the sky and over every living creature that moves on the ground.”
29Then God said, “I give you every seed-bearing plant on the face of the whole earth and every tree that has fruit with seed in it. They will be yours for food. 30And to all the beasts of the earth and all the birds in the sky and all the creatures that move along the ground—everything that has the breath of life in it—I give every green plant for food.” And it was so.
It doesn’t say anywhere we will be ruling over any other planet. It does say that we (as men) are given authority to rule over the animals, plants and trees on this earth. We are also commanded to “fill and subdue” this earth, meaning to live all over on it, and control it, to make it function well; to create order, and good functionality on it.

So, Biblically, there is no reference on living on other planets.

From a science point of view, living long term on other planets will also not work out.
From the harsh environments, not allowing mankind to go outside, lacking sunshine (vitamin D deficiency),
Overwhelming radiation, that can cause long term DNA issues (cancers, miscarriages),
To the fact that every planet we could possibly live on, does not have all the nutrients we as humans need to survive!

A lot of science is spent in researching how spacecrafts can overcome gravity,
How more stuff can be shipped out of orbit, for a lower cost, and less and less fuel is used.
Research is done on making life on another planet bearable. Living in steel tubes on the surface of Mars, for 6 months, is one of them.

Mars still gets regular impacts of smaller comets, smaller astroids, and space debris (rocks, …). if one of them would fall on a science center, it could cause catastrophic results.
But research is done to lower chances of this happening.

From a technological point of view, everything ‘seems’ to be in order…
But I think they’re forgetting how many diseases we already have on earth, most of them resulting from malnutrition.

It could be as simple as having a diet lacking copper, zinc, iron, or chromium. A lot of trace minerals are needed for the body to survive, that are ONLY found on earth!

So even if we would find a planet, that would be in a reachable distance from our planet, that would preferably have some kind of atmosphere where we could survive for a while, and possibly even have water,
Where we are shielded from cosmic debris, and radiation, and are probably living underneath the surface, due to the extreme temperatures;
my estimation is, that we would never be able to live in other planets for a very long time.
Like the moon, it was nice to go there; but we never went back.
Not only because financially, but because… yes.. there’s nothing to do there!

A hostile place, without any resources we can use to multiply, and live a prosperous life like on earth.

As a child I had hoped we would find a second earth soon, in my lifetime!
It would be an adventure of a lifetime!
Elon Musk, a guy with a lot of money, may want to give this a shot, but my predicament is, no matter how much money he will throw into this project, it’s not going to work.
And though it might be possible to survive on some planet for a while; survival is far from living.

His analogy of “backing up your data on another harddrive”, referring to backing up humans on another planet, in case something would happen to earth; is more like backing up SSD or harddrive data on an old 3.5″ floppy drive, which has data corruption over the course of a few months to years!
The data on the harddrive is more safe than on the floppy.

And humans aren’t ‘copied’, or ‘backed up’ to another planet. They are moved. That means every string of DNA going to another planet, is removed from this planet, with possibility of it going corrupt, or lost.
