Venus is very hot, almost 800 degrees (Fahrenheit) at the surface. Venus also has a very heavy atmosphere. With a heavy atmosphere, there is a lot of pressure. A sophisticated lifeform such as a human-being would need a heavy shell for protection, just as humans going to great pressures under the sea in a submarine need.
We know, however, that there are life forms on earth which can survive in very harsh environments. Bacteria and very simple plant life can survive in unexpected places.
Because of the very high temperatures, the environment of Venus seems unfriendly toward life as we know it on Earth. More exploration of Venus is needed to determine if life was once present there.
