According to the most accepted geological theories, India once belonged to an Island continent called Gondwanaland and was separated from the Eurasian continent by the primordial Tethyan ocean. One billion years ago, the Aravallis, whose eroded remnants are visible around Delhi, formed a chain higher than the Himalayas today. Over millions of years these mountains suffered the forces of erosion and their sediments were deposited in the Tethyan ocean. Then 140 million years ago, India began it's northward movement, on a collision course with the Eurasian continent.

The point where the two continents were joined is known, appropriately, as the Indus- Yarlung Suture zone, marked by the courses of these two greatest rivers of the Kailash. After 60 million years, the Indian and Asian plates became closely welded along this suture zone. The northward movement of India continued but at a slower rate - 2-3 centimeters per year.

And what birth pangs.... as a result of the collision itself, and the related contraction of the Tethyan ocean, all the rocks of this area, from the mountains of then northern India to the oceanic crust, and the deep sea sediments of the Jurassic and Cretaceous ages, joined in the formation of the Himalayas.

The himalayas mountain came into being when a fold known as geosycline which is formed by a down fold as a result of downwarping due to the weight of the materials deposited after which they are acted upon by forces from the earth (compressional forces) which uplifts them forming fold mountains and himalayas being a result of the whole process.

this is the concentrated answer:

1) long ago,major parts of the world were joined together as gondwana landmass.soon,it began to break up and drift in all directions.

2)the indian plate dashed towards the eurasian plate with such a force that the ocean bed of the adjoining Tethy's sea got lifted up to form the himalayas.

The himalayas came into being when india seperated from antartica by tectonic drift. it then collided into asia, whch pushed up the himalaya mountains. these mountains ares till growing today.
