I can swear to you as bad as anyone, but I wouldn't do that in public mate. Wake up.
You said "If death is for definite end of all the livings, then is there meaning in life?"
Death is the end of the life of an organism. Why would that challenge meaning?
Then you said "How do you define death, and meaning of life?"
Death is the cessation of life.
The definition of life is more complicated.
It is the various and multiple organisations of matter found on planet earth which lead to the following characteristics:
Cellular organization: All living things are composed of one or more cells, which are the fundamental units of life. These cells contain various biomolecules and perform essential functions to sustain life. The possible exception if viruses which exploit the cellular structure of other organisms to fulfil the other criteria of living systems.
Metabolism: Living organisms carry out metabolic processes, which involve the conversion of energy, food and molecules from the environment to maintain life-sustaining activities, such as growth, reproduction, and responding to the environment.
Homeostasis: Life maintains internal stability despite changes in the external environment. Organisms regulate their internal conditions (like temperature, pH, and concentration of substances) to sustain life processes. Also balancing the needs of energy usage and storage, and the maintence of living systems through hormones, enzymes and in some cases nervous impulses.
Growth: Living organisms can grow and develop, increasing in size or complexity over time through controlled, organized processes. Although crystals can grow they do not fulfil any of the other criteria
Response to stimuli: Living organisms can perceive and respond to changes or stimuli in their environment, allowing them to adapt and survive. Sometimes called irritability. This includes awareness of things such as food, light and danger.
Reproduction: Living organisms can produce offspring or replicate themselves, passing genetic information (DNA or RNA) from one generation to another. This can be sexual or asexual. Reproduction obviates the potential cessation of the organism through death. Death opens up the way to renewal of the genetic material in new organisms and is the primary way that species evolve.
Evolution: Living organisms show the capacity for genetic variation and change over successive generations through natural selection or other mechanisms, leading to biological diversity and adaptation to the environment.
This is what "life" means.
So I have comprehensively answered your questions.
So why would the existence of death be a challenge the meaning of life?
