a lot of people think that science can explain everything but other people do not agree. let us start by considering pros and cons of it.

the first thing that needs to be said is that science predicts earthquakes and studies many other natural events. it helps people. it makes our lives easier and safer.   secondly science studies various aspects of human biology and the origin and development of the human race. people can cure many diseases.they can invent new machines.

on the other hand, we observe that scientists can’t even explain some historical facts. what is more, some species are not studied in biology. every year doctors meet a mysterious virus. moreover, science can’t go into far space. there are many mysteries. nobody saw aliens.

to draw the conclusion, one can say that there are different opinions about possibilities of science. i think that not everything can be explained.
