At least two dozen planets outside the solar system might be better for life than Earth.

Why do astrobiologists keep on assuming that there are other planets that
might be conducive to life, when in fact, they have found none that even remotely fits the requirements for life as the earth does ? They continue to conjecture of the
possibility for life to exist elsewhere, but have no hard data to support their "belief", just further hypothesis.
Here is where an ancient proverb comes into play, that says: "Like clouds and wind that bring no rain, is a man who boasts about a gift (of
proving that there is material life elsewhere or that other planets meet
all the critical requirements) never given".(Prov 25:14 in the Bible) And what are some of the critical requirements for material life to exist ?
(1) the temperature has to be "just right" or in the "comfort zone", not extreme, such as what we find on the earth,
(2) and for the temperature to be "just right" requires a precise distance from the sun, which is 93 million miles, for just five percent closer and the earth would not be able to sustain life, being too hot, and one percent farther away and the earth would be a frozen wasteland
(3) the exact size of the earth, for if the earth were just slightly larger, hydrogen, a light gas, would not escape at the proper prescribed rate, being held on ground level, rendering earth to become a dead zone, and if the earth were just slightly smaller, surface water and oxygen would escape the earth's gravitational force, leaving us "high and dry" so that life would be snuffed out, and thus for a planet to sustain life as we see on the earth requires a precise and delicate balance not found anywhere else.
(4) a planet has to have an atmosphere that has the precise proportion of oxygen (21 percent of the atmosphere for humans, animals and other organisms to breathe as the Hebrew word
nephesh designates that literally means "breather" at Genesis 2 in the Bible) to nitrogen (78 percent of the atmosphere for plants to grow by means of a nitrogen cycle through certain bacteria, in which if there is none, root systems and plant growth is stunted, causing photosynthesis and life to cease and also provides a "safety net" of inert gas against sudden outbreaks of fire due to high concentrations of oxygen) to carbon dioxide (about 0.4 percent for plants to extract the carbon and release the oxygen for "breathers" to breathe) to begin with.
Just as a modern car is composed of about of about 30 thousand "pieces", and each must exactly fit precisely together as "one" for the car to function well, or otherwise, there are "problems", so of the earth, but its precision far exceeds that of a modern automobile, for it is our "home" in the cosmos, that must keep "on ticking" exactly as it is or life would cease.
Any deviation and astrobiologists run into serious problems or the anthropic principle. Over thirty years ago, astronomer John Barrow and mathematician Frank Tipler studied “the ratio of the Earth’s radius and distance from the Sun.” They concluded that human life would not exist “were this ratio slightly different from what it is observed to be.”
Professor David L. Block (elected a Fellow of the Royal Astronomical Society of London at age 19) notes: “Calculations show that had the earth been situated only 5 per cent closer to the sun, a runaway greenhouse effect [overheating of the earth] would have occurred about 4 000 million years ago. If, on the other hand, the earth were placed only 1 per cent further from the sun, runaway glaciation [huge sheets of ice covering much of the globe] would have occurred some 2 000 million years ago.”(
