What if life ?
any body explain in very short lines

Did you mean "What is life?"
If so, life is a characteristic that includes biological genes, growth, reproduction and so on.

Your question is very important question and researchers who are working on consciousness care a lot about this question. If this is true, you and only you would be real and all the rest of us we would be bots in your dreams , our job would be to entertain you and make your dream richer and intense. I think this is an absurd proposition because there are a lot of lives and stories that are taking form beyond you and your world besides that the world should stop existing by your death. This leaves us to think life is a common dream that we share this is more logical but in this case this proves how small we are because we will never know which is the real world, this life or the after life . We are just stuck and in my opinion you will never know and that will have no significance.

Jonathan swift is using a satirical approach to make awareness to the fact that there are too many beggars (which include women and young children) on the streets. his solution? eat the children. yes this sounds like the craziest thing in the world but it's a solution. the children could be sold to landlords to pay rent and the family could have stuffed bellies. he lists the advantages, disadvantages, and the rebuttal to the disadvantages to support his claim. he also suggest what age should be the highest price and how to cook them. in the end, he excludes himself from his solution. all i all, swift uses a satirical approach to get people aware of the beggars that flood their streets.if you need more for "a modest proposal", i am here.
