Life was created only once, about 5 billion years ago. Life is being perpetuated by the living beings, ever since.Life begets life is a common adage. Virchow said it.Life is perpetuated through reproduction, whether sexual or asexual.
Creation of life occurred by a process called chemosynthesis which involved formation of smaller compounds in the ocean with the help of lightning and powerful sun rays as the sources of energy.Water vapour and nitrogen were made into ammonia and then amino acids and then nitrogenous compounds. they formed proteins and nucleic acids respectively. When the power of auto-catalysis and replication developed life originated. This is also called biopoiesis.

It is based on the principle of duality - like - black/white; dark/bright; day/night; anger/love; male/female etc. etc.
As Newton said, for every action, there is a reaction. Likewise, for every being in the world, there is exactly opposite virtue.
When there is a conflict between the two, a new phenomenon is created.
For example, ligtning amongst the clouds.
Based on the same principle, a new life is created when there is a conflict between the one and the opposite in the case of living beings.

thousands and thousands years ago according to life sciences there was a blast from which earth created and the whole earth was very hot and there was no significance of life, but after a very big leap of time in the water which exist on the earth get first DNA (No body knows from where it gets created ) then it first get develop in to the unicellular organisam , so the process gone continues and we r here at this stage on earth

Through a biological process handed down through the millenniums by years of evolutionary growth and achievement. Theoretically it starts out as amino acids that mix with peptides in the cosmic soup or something of that nature that would eventually evolve into single cell life.

in the uterus of a female, there exists 2 fallopian tubes. in one of these fallopian tubes resides an ova (haploid) in each cycle. when the male semen (containing sperms which are also haploid) enters the female reproductive tract, the sperms swim towards the fallopian tubes. by an unknown law of nature, the best of the best sperms fertilizes the ovum. then, the 2 nuclei fuse, producing a diploid no. of chromosomes. the zygote which is thus formed repeatedly divides mitotically to produce a full grown individual.

There are two possibilities
1. GOD
2. Evolution
But for evolution one organism is needed but the question is from where did that organism came ?

Creatures have sex, eggs are fertilised in the female body, DNA interchange and synthesis takes place. Cell formation starts.

after various climatic changes
chemical rxns,
amino-acids hv formed
they combine to form proteins
n they combine to form cells
cells - organisms
that's how life's formed
