Some scientists think that there are intelligent life forms on other planets and messages should be sent to contact them. Other scientists think it is a bad idea and would be dangerous. Discuss both views and give your own opinion.

Thanks to the advances in astronomy,

people

nowadays have the ability to explore outer

space

, where was unreachable in the past. In light of

this

, some

scientists

are passionate and cannot wait to search the universe.

However

, other

scientists

argue that

such

activity is worrisome and that

this

may lead to appalling ramifications. In my opinion,

people

should be encouraged to explore the universe if any opportunities come and think that

humans

should have the spirit of adventures when involved in

such

a new area.

First

of all, optimistic

scientists

maintain that humankind has to explore outer

space

for any intelligent life. They believe that

such

activities can bring about positive effects on

humans

.

For example

, in the 18th century Napoleon, an explorer, took his sailers aboard, starting their cruise to an unexplored world.

As a result

, they found a new world, which turns out to be North America. If at that time Napoleon had been less courageous and been conservative, the American civilisation, or the whole world, would have been regressed several decades.

On the contrary

, pessimistic

scientists

warn that sending messages to outer

space

has latent threats.

This

is because

such

behaviour may expose the location of the earth to high-intelligence creatures, possibly resulting in the worst-case scenario, the massacre of

humans

. In order to prevent

this

devastating consequence from happening, astronomers must stop broadcasting or transmitting any signals to the universe. In conclusion, while some

people

think that trying to communicate with aliens will put

humans

on the verge of extinction, others believe that

people

cannot lose

this

precious opportunity to make progress in human history. From my point of view, in regard to exploring outer

space

, the advantages outweigh the disadvantages.
