Does grammar still exist.
Depends on how you define aliens.
Little green men
Microbes
Immigrating foreigners.

Probably. In fact, if we live in an infinite universe, then it is certain that there are other lifeforms out there - some of them identical to you except they had a different breakfast on 22nd April 1992.
The problem is that these identical and near identical copies would be so far away that over the life time of the universe light will never be able to travel from here to there.
Life began on earth pretty much as soon as it could - shortly after the planet had cooled down enough. So it seems probable that on other planets simple life forms have evolved.
One of the big bottlenecks for life on earth was the development of multi-cellular creatures. That took a very long time to arrive... and we can't tell how likely it is that multicellular life has evolved elsewhere. So it may be that most off earth life is bacteria like.
I do not believe that aliens are travelling to earth, flying through the atmosphere and mutilating cattle or kidnapping texan farmers and *cough* probing them. Any aliens capable of travelling here would surely have better technology than a rectal probe, and would be capable of remaining unnoticed if they wanted.
The problem is the Fermi Paradox. If there are aliens out there, why can't we see them? It would only take a few million years for a species to colonise the galaxy, even travelling at sub-light speeds. And a technologically advanced culture should leave signs that we can spot - they would be able to alter the evolution of stars, even enclose them to make use of all the energy a star produces. But we don't see any of this large scale engineering, so the conclusion is that if there is other intelligent life out there, it never makes it beyond its own solar system.
I hope I'm wrong, but I'm forced to conclude that while life may be abundent, we won't be chatting with any neighbours any time soon.

We exist. Over the centuries, your planet was a curious place to visit once or twice and was not considered very interesting . Sure, your wars showed us how undeveloped you are as a species. Your infantile,(in cosmic terms) dependence on god concepts does not bode well for you and neither does your penchant to breed beyond your planet's ability to sustain you. We are now showing an interest in you because it is not often that we get to observe a species commit suicide. You are so close to maturing as a sentient species and it will be a shame to see you kill yourselves. There are just not enough of you becoming rational enough to force the issue. You let the least among you determine your fate, so be it.

If life can exist...it Will. Nature abhors a vacuum, and will fill it with life if it is possible. Even the "emptiness" of space isn't necessarily empty, there could be and probably are microbes that can survive their environment, possibly containing the "seed" of life that could be transferred to an otherwise empty planet. Definitely something to think about.

i know they r . because if we r there in 1 solar system having 1 star then there r 100 billion galaxies each having 100 billion stars. So there should be billions of solar systems. Trillions of planets. Some planets would be definitely having similar atmosphere like Earth

Yeah, it seems likely. Even if it is only very basic life.

Yes they do exist! Do you think Earth is the only planet with life in so large sooooooooo huge universe. If you think so, you are definitely wrong. Check this out as a proof :

Can you ask in understandable English? (grammar!!!)
And what do you mean by "aliens"?
You need to specify.
