There was life long before the dinosaurs. Insects, crustaceans, fish, amphibians and certain reptiles all were here before the dinosaurs. One of the most abundant was the trilobite, a primitive crab-like creature distantly related to the modern horseshoe crab. And then there's the coelacanth, a fish that still exists today that saw the dinosaurs come and go. Dinosaurs first appeared about 165 million years ago. There has been life on earth about 2 billion years. In a way, dinosaurs were fairly recent creatures.

Yes, the dinosaurs did not just pop up one day. It started out with bacteria and evolved from there over millions of years. That is what the evidence points to.
Here is a breakdown of the geologic periods. You can click on the different periods and get info about it. Each article usually has some information about the prevalent life of each period.

Dinosaurs happened during the Mesozoic era which covered the Triassic, Jurassic, and Cretacious periods. You can find fossils all the way into the Cambrian period. There was life prior to that but it is much harder to find fossils because they are usually soft bodied creatures or microscopic animals which usually left nothing to fossilize.

"Did existence exist even till now the Dinosaurs?" the overpowering majority of the historic past of existence in this pre-dates the 1st visual charm of dinosaurs. They first pop up approximately 3.8 billion years after the earliest organisms. "replaced into there any mammels, any form of existence for the period of Pre-Cambrian (till now the Dinosaurs) or replaced into the Earth nevertheless being made?" No mammals, yet numerous different Precambrian existence. Mammals scurried onto the scene sometime only before 215 million years in the past, and non-mammalian synapsids (which risk-free the ancestors of mammals) are first customary from the top Carboniferous.
