LIFE EXISTENCE IN OTHER PLANETS
Introduction
When we hear of life, it is hard to think of any other planet other than Earth. Even then,
that does not mean that people do not work towards finding if there is life on other planets: and is
there? In this line, we cannot forget that most of what we know of living organisms is based on
what we have seen on Earth or studied from Earth and the existence of life. In the 21st century,
the drive to establishing if there is life on other planets has been on the rise. There has been
advancements in other sectors like technology which has aided in this research. Also, we hear at
times people referring to aliens and how they will attack Earth at some point. Therefore, if we
can indeed prove that there is something like aliens, then it would be a great step towards the
establishment of life on other planets out there. According to Crater, 2009, people have been
dreaming and working towards discovering intelligence in other planets, and every day is a
chance to look into it in hopes of coming up with a conclusive answer. Over the centuries, we
have been sending electric signals into space, hoping that if there is life there, it will get to them,
and they can respond to the bubbles that are sent. In as much as there has been no response, as
technology improves, so does the electronic signals sent increase and improve. There could also
be the chance that the electronic signals have been answered in a language that we cannot
decipher, or the existence of other life may be at its early stages hence no much concrete
evidence to support it for now. Therefore, the purpose of this paper is to look into whether there
is the existence of life on other planets and, if so, what evidence supports it.

Search for Life
Notably, the chances of discovering life outside Earth keeps on increasing every day with
all the other advances that we have made in other sectors. As we continue searching for
extrasolar planets, then we continue increasing our chances of discovering them. As it is we do
know of various habitable zones that are in existence especially in the milky ways in the stars.
Therefore, if we were to discover that there is indeed life here and the organisms get to reproduce
and undergo other changes of natural selection, then that would be a win for the search for
habitable or life existence in other planets. Discovering of other life outside the realm of Earth
would be very exciting, especially if it would be possible to obtain DNA and RNA from the
organisms so that there can be a comparison to seeing if there is any relation to the organisms
already existing on Earth. During the formation of Earth, there is a chance that RNA and DNA
viral-like replicons...
