Life And Death Of Planet Earth

the universe is too infinite .are there more earths containing human beings ?

is only the earth containing the wise human beings? if there were more planets having life , then our consciousness should had told us before , because on earth too much scientists and religions exist which are saying that they are conscious of everything.
are people living on earth just the people of earth only ? if after death consciousness never dies, then no -one after death took birth on another planet if life is existing there?

Just to clarify, according to modern physics, the universe is not infinite.

The universe is certainly very very big, and it is also expanding. However at any one moment in time it is of a finite size.

Some people argue that if the universe is infinite, then anything that can exist will exist somewhere, no matter how improbable that thing may be. However, as the universe is not infinitely big, then this logic does not apply.

However, it is possible that other life does exist somewhere in the universe, though we are very unlikely to ever find it. The nearest star to earth (other than our own sun), is 4.2 light years away. So, even if we could travel at the speed of light, which we very much cant, it would take 4 years to get there. So, if life does exist somewhere else, then it is probably millions of light years away, meaning it would take millions of years to get to it, even if we could travel at the speed of light.
