No one has an answer for it, Biology says billion of years ago some multiple chemicals got together and made the first molecule self-sufficient to replicate itself. We humans are somehow linked by evolution to those early biological molecules. But the question still remains unanswered, How were those multiple elements present on earth ? More over what prompted them to replicate and arrange themselves to resemble life.
There are theories out there but still no answer.

Discuss ???
No stupid answers

It is a basic question of human life, philosophy, science and religion all have solved this question in their own way. For example philosophers say that the world is developed accidentally, you have mentioned scientific logic, whereas, different regions have different beliefs. However, I will give you the answer in accordance with our region deen-e-Islam. There are some questions which are only known to Allah. He is the Omnipresent, Omnipotent and all knower. Allah Says in the Holy Quran Chapter 31 Surah Luqman Verse 34:34 Verily the knowledge of the Hour is with Allah (alone). It is He Who sends down rain and He Who knows what is in the wombs. Nor does anyone know what it is that he will earn on the morrow: nor does anyone know in what land he is to die. Verily with Allah is full knowledge and He is acquainted (with all things).

Therefore, we just know that Allah has created adam and yielded Bibi Hawa from his body. Hence, Allah says: "O mankind! Surely We created you from dust." (Qur'an 30:20). We just know that we are created by dust and the beginning of life started from dust material.

Dear
Basically you are right,
Everyone gives theories, Allah Almighty is the best in theories and practicals, But the science never believes in religions, Curiosity of scientists deny to the verse of Allah that dust possesses no sort of Bio-related molecule which can turn into living organism.
Therefore, you are right everyone possesses their own perspective but
Allah Almighty is the best Planner.

If dust does not posses the intensity to fetch the life then how a plant grows in a dust after getting water?

Let's just not make it personal folk
But, Dust also if stucks in your skin pores you have in your skin then its severely dangerous, Dust is a symbol of dirtiness in our atmosphere but those scientist don't know that "Man is dust to dust".

And plants grow in dust it is because to support their roots so that they may penetrate to deep earth for water and nutrition.

Evolution. Just found this article, might be useful to you

Which came first, the chicken or the egg? That my friend is your answer.

I had read an article, in that there was written that first came egg. Once upon there was a bird (I forgot its name), it fetched a new kind of egg, that egg was of chicken, then the generation of chicken was started. It was a doctor of New York Universtiy, who worked on this topic and proved it with facts and figrues. So, we have answer of this question. You can search it out on net, you will probably find that article.

Now that is quite the conundrum. The human species is quite the marvel. in our haste to prove our own personal worth we do quite the absurdity to stoke our own egos. The unfortunate fact, however, is that we are extremely short sighted and can not infact see what lies underneath our nose; hence the conflation of our selves.
My dear friend, before you try to negate someone again do something first-ponder. Ponder over the fact that have you become so insecure that by negation you increase your own self esteem.
Concluding my advice, let me give you the answer to your question. Quoting your own writing "once upon a time there was a bird......fetched an egg....the egg was of a CHICKEN......"
Do you see the irony? Because i sure as hell do.

Allah made the first pair of every creature that roamed the earth from the biggest beasts to the smallest molecule. the pairs then reproduced and the population expanded.

And it is He (The One) Who extended the earth, and made therein anchorages (mountains) and rivers; and of all (plant) products He made therein two in pairs.} (Ar-Ra`d 13:3)

Behold, for those who believe there are (myriad) Signs in the heavens and the earth and in your own creation; and in the animals which He spreads out over the earth too there are Signs for those endowed with sure faith; and in the succession of night and day, and in the provision that Allah sends down from the sky wherewith He gives life to the earth after it had been lifeless, and in the change of the winds: (in all these) there are Signs for people who use reason. These are Allah's Signs that We rehearse to you in Truth. In what kind of discourse after Allah and His Signs will they, then, believe? (Surah Al-Jasiyah 3-6)

You can search it out in Quran.
