Are scientists sure about evolution?

Well, some think they are. But no. There is no evidence for evolution yet. Often we are given ,as an example, a finch with a short beak and one with a long beak. It is claimed that one of the birds evolved. Well maybe so, if thats what you mean by evolution. Thats only adaption to the environment. But an example of evolution would be if one of those finch's laid an egg and it hatched into a Komodo dragon.

Other than you using the common deceit of conflating the origin of life with evolution that begins with life, your efforts to portray abiogenesis as improbable fails at every step.

"...we need a favorable environment for life to evolve and be sustained."

If life emerges, it must be compatible with the atmosphere. Even then, a crisis arose as plant life produced enough oxygen to be toxic. Life had to adapt to this little snafu.

"We need a means of constructing the building blocks of life."

Lightening and ultraviolet light can both trigger bond formation.

"Some the simple molecules must be assembled into biologically useful large molecules."

The first "useful" large molecule would be one that catalyzes the formation of other macromolecules.

"Energy conversion must be constructed."

Not true at all, since energy is introduced into the biosphere (of in this case, "prebiosphere") at a tremendous rate. Even before photosynthesis became a source of energy, the chemical energy released by volcanic vents would suffice.

"...all these molecules and systems must be assembled together to form a highly complex living cell."

No. They have to form into a simple living cell. This cell has no competition, so any crude mechanisms that work have survival potential. If it replicates successfully once every thousand years, it doesn't matter. It succeeded.

Creationist's simply ignore or distort the evidence for evolution in order to force it to comply with "their" interpretation of the bible.

Radiometric dating for example is discarded because it doesn't fit "their" view.

There are 2 million microbial, plant and animal that are all the results of evolution, what unites all these diverse life forms is that all organism's carry their genetic information in the DNA molecules within the cell.

That is a FACT and that means that all organisms are related by descent.

Of course this is all denied by the creationist's.

Here are a few things for the creationist's to think about:

If the earth is only a few thousand years old (the young earth claim), why does light travelling at 186,000 miles per second take 100,000 years to cross our own galaxy ?

Was GOD just trying to throw us off by creating the light that is on it's way to earth as we speak, that is millions of light years away ?

What does that say about the earth and the solar systems actual age?

That it is much older.

The decomposition of organic matter to petroleum(fossil fuels) is known to have taken millions years.

The contintental plates which formed our oceans and mountains also took millions of years.

Life has been evolving for billions of years.

What about the fossilized bones of our ancient ancestors?

A perfect example of our own evolutionary stages is the unbroken sequences of progressively more modern features such as increased cranial capacity, smaller faces and teeth, larger body size, etc.......was GOD simply mimicking evolution or testing your "faith" ?

Again, the only people who doubt evolution are the ones who don't understand it.

There is no random, there is no instant burst of complexity- each step gradually builds on the step before.

Yes, scientists are as 100% sure that the evolutionary process occurs as they are sure the earth goes around the sun.

Yet, people of religious conviction like to deny that evolution exists- just like they denied that the earth goes around the sun.

Isn't that silly?

Evolution has been observed, it is a fact, and it is the ONLY explanation that fits every single bit of evidence.

All of those lovely little trinkets you read on the creationist web pages have been refuted long ago.

Yet, for some reason, people keep digging them up.

Yes, that's silly.

Yes, they are sure. Each step is actually rather small, and has been shown to happen.

We have seen amino acids and peptide chains spontaneous building in nature. That is not so wild a leap.

There are processes that create self-propagating chains. That is also quite a small step. Once you have several of those processes, they compete for resources. It is natural for the most efficient to win.

Once you have competing processes, you have a biological system. This started long before the first actual cell. Cell walls were just another small step in the process that contributed a bit of a competitive edge. We see remnants of the pre-cells in mitochondria, which have their own DNA and lived separated before cells came to be.

Sorry, but scientists have already shown how each step in the development of life was a relatively small one. Your premise is false.

Im not surprised either, seeing as evolution has ABSOLUTELY NOTHING to do with the abiogenesis of life on earth.

Of course, GOD DID IT is invoking the God of the Gaps theory. Since science doesnt have an answer, then that means God did it. Intellectually lazy and dishonest. Do you honestly think we will EVER know the truth if you keep chalking it up to an imaginary being? Who needs to search for the truth, when you lie and state you already have it?

Yes. Evolution is as certain as anything known to science. Most of what you wrote however pertains to the origins of life, which is a completely different subject. Evolution considers only the development of new species from pre-existing species, not the initial origins of organic molecules or life itself.

.

Wow, you have no concept of evolutionary biology in the terms of cosmological time. We are talking about BILLIONS of years of development before the tiniest organism one could call life appeared. Over the next few billion years chemicals and proteins were added to these living things, creating more and more complex life. Man (homo sapiens) by comparison has only been in existence less than 200,000 years.

the origin of life is still a mystery, as you pointed out. This has nothing to do with evolution, which deals with how life evolves. Yes, scientists are sure about evolution. But not about the origin of life.

You are all mixed up. Darwin's theory of Evolution is not about the origin of life. That evolution has happened is a fact. Exactly HOW it happened and how life originated are still open to question.

That isn't evolution. That's abiogenesis and is a different part of biology. Evolution deals with how living creatures change and mutate to gain an advantage in their environment to continue passing on their genes.
