Dunno much about UFO. but I heard most sightings in Malaysia are actually not UFOs...but what if UFO really do exist? I mean there gotta be another living organism/creature/etc out there right?

if these UFO is really another world, why couldn't they just land in front of KLCC tower and wave to fellow humanians?

We have higher chance that earth being bombarded with asteriod causing human kind of extinction than finding UFO or alien visting the earth.

Even alien is within the same galaxy with earth, milky way, under current law of physics speed on light, it might take hundred of thousand and million of year to reach us.

Human kind have how many year of history? several thosand year, compared to millions year needed to travel, the probability is starting with low point already, somemore, galaxy is so enormous wide, what is the chance alien spotting earth so probability goes even lower.
A thousand year is a relative too small time frame in universe standard.

I don't dispute there are potential life form out there (can be a lot of form, not necessary must be identical with human kind, a head, a body, pair of arm and leg), just the probability of alien reaching earth is not promising at all.

hmm... if they are spying on us.. they should know their superweapons and technology is far more superior than us, so would not be afraid of losing to the US.

The topic here is about UFO. I do agree alien do exists. But those UFO that appears on earth is all fake. They have not discovered us 'yet'... i believe

if UFO exists, then what is their purpose on earth? with their so advance technology, surely there is nothing that what we know and they don't know.
tell me, what human attributes that could probably impress our UFO friends...?

I am not rejecting attempts to discuss but I am dismissing idiots who dismiss and explain away things without convincing evidence.
