Are you not placing your faith in men and their educated guesses?
No one has seen an eye evolve, have they? Are you not having faith in what you haven't seen, nor can see.
Looking also at the fact that the complexity of life, was seen from the very start, is a headache as to how complex life evolved. Of course, they seek to fix these with their various theories. They always do.

How did complex life evolve?
Scientists have long pondered the question of how simple “prokaryotic” cells, like bacteria, which are little more than a membrane-bound sack, evolved into more complex eukaryotic cells, which contain numerous internal membrane compartments.
Why complex life probably evolved only once
The universe may be teeming with simple cells like bacteria, but more complex life – including intelligent life – is probably very rare. That is the conclusion of a radical rethink of what it took for complex life to evolve here on Earth.
It suggests that complex alien life-forms could only evolve if an event that happened just once in Earth’s history was repeated somewhere else.
All animals, plants and fungi evolved from one ancestor, the first ever complex, or “eukaryotic”, cell. This common ancestor had itself evolved from simple bacteria, but it has long been a mystery why this seems to have happened only once: bacteria, after all, have been around for billions of years.
There are so many baffling questions for the naturalist that it calls for one who refuses to acknowledge the designer of life, needs to put faith in educated guesses
An age old question? Or has it already been answered?
How Did Life Arise on Earth?
...some scientists think life appeared the moment our planet's environment was stable enough to support it.
The earliest evidence for life on Earth comes from fossilized mats of cyanobacteria called stromatolites in Greenland that are about 3.7 billion years old. Ancient as their origins are, these bacteria (which are still around today) are already biologically complex - they have cell walls protecting their protein-producing DNA, so scientists think life must have begun much earlier. In fact, there are hints of life in even more primeval rocks: 4.1-billion-year-old zircons from Western Australia contain high amounts of a form of carbon typically used in biological processes. [7 Theories on the Origin of Life]
...scientists are still far from answering how it appeared.
"Many theories of the origin of life have been proposed, but since it's hard to prove or disprove them, no fully accepted theory exists," said Diana Northup, a cave biologist at the University of New Mexico.
The answer to this question would not only fill one of the largest gaps in scientists' understanding of nature, but also would have important implications for the likelihood of finding life elsewhere in the universe.
Lots of ideas
Today, there are several competing theories for how life arose on Earth. Some question whether life began on Earth at all, asserting instead that it came from a distant world or the heart of a fallen comet or asteroid. Some even say life might have arisen here more than once.
"There may have been several origins," said David Deamer, a biochemist at the University of California, Santa Cruz. "We usually make 'origins' plural just to indicate that we don't necessarily claim there was just a single origin, but just an origin that didn't happen to get blasted by giant [asteroid] impacts."
Most scientists agree that life went through a period when RNA was the head-honcho molecule, guiding life through its nascent stages. According to this "RNA World" hypothesis, RNA was the crux molecule for primitive life and only took a backseat when DNA and proteins - which perform their jobs much more efficiently than RNA - developed.
"A lot of the most clever and most talented people in my field have accepted that the RNA World was not just possible, but probable," Deamer said.
RNA is very similar to DNA, and today carries out numerous important functions in each of our cells, including acting as a transitional-molecule between DNA and protein synthesis, and functioning as an on-and-off switch for some genes. [Extreme Life on Earth: 8 Bizarre Creatures]
But the RNA World hypothesis doesn't explain how RNA itself first arose. Like DNA, RNA is a complex molecule made of repeating units of thousands of smaller molecules called nucleotides that link together in very specific, patterned ways. While there are scientists who think RNA could have arisen spontaneously on early Earth, others say the odds of such a thing happening are astronomical.
[Despite clear evidence of design, requiring a designer, many put faith in their theories.]
The anthropic principle
But "astronomical" is a relative term. In his book, The God Delusion, biologist Richard Dawkins entertains another possibility, inspired by work in astronomy and physics.
Suppose, Dawkins says, the universe contains a billion billion planets (a conservative estimate, he says), then the chances that life will arise on one of them is not really so remarkable.
Furthermore, if, as some physicists say, our universe is just one of many, and each universe contained a billion billion planets, then it's nearly a certainty that life will arise on at least one of them.
As Dawkins writes, "There may be universes whose skies have no stars: but they also have no inhabitants to notice the lack."
Shapiro doesn't think it's necessary to invoke multiple universes or life-laden comets crashing into ancient Earth. Instead, he thinks life started with molecules that were smaller and less complex than RNA, which performed simple chemical reactions that eventually led to a self-sustaining system involving the formation of more complex molecules.
"If you fall back to a simpler theory, the odds aren't astronomical anymore," Shapiro told Live Science.
Trying to recreate an event that happened billions of years ago is a daunting task, but many scientists believe that, like the emergence of life itself, it is still possible.
"The solution of a mystery of this magnitude is totally unpredictable," said Freeman Dyson, a professor emeritus of physics at Princeton University in New Jersey. "It might happen next week or it might take a thousand years."

@viole, and Cacotopia... So what are you guys trying to say, that your faith is better?
Consider the OP.
The definition for design is clear to see - no need to read between the lines.
All life on earth fit into the definition of design. Therefore all life on earth was designed, and thus has a designer.
This explanation for the complex life forms on earth, is simple - no rocket science needed.
Doesn't that make my faith sound?
Psalm 100:3 Know that Jehovah is God. He is the one who made us...
We do not have faith. We have evidence. These are two completely different things.
And we generally all agree. You do not even manage to agree between Allah, Jesus, Apollo, Kali, the great Juju or Whomever your fantasy makes up. Which is quite embarassing. Or it should be to the rational mind.
