Personally, I don't. There are several factors that contribute to the way our planet is and the life that exists on it. First of all the relative size of the Sun, Moon and Earth. The Earth has a moon that is 1/4 its own size and that effects the amount of gravity pulling on the Earth. Also, we're a nice distance away from the sun, not too close to burn up our atmosphere and not so far away that the heat from the sun can't give us proper lighting and the right amount of heat and all those nutrients we get from the sun. And, wow, there's so many more things that would just make it impossible for there to be another planet just like Earth. I could go on forever!

with possbily over 100 000 000 000 000 000 000 000 000 stars out there, I would say that we have a good chance of having an earth like planet somewhere.
even if there was a POINT 0000 000001 % chance we'd still have 10 000 000 000 000 000 possibilities.
and POINT 0000 000001 % of THAT is still
1 000 000
and 1 % of that is
10000
sounds like good odds to me.
but "exactly" is a key world. that chance is ZERO

Exactly? No. If for no other reason than location.
But a close enough approximation that it would not make a difference? Yes.
In our galaxy alone there are billions of stars (suns) and we already have found over 250 planets outside our own solar system. And there are other galaxies even bigger.
As far as the distance from the sun, look up Titius-Bode Rule. According to that, planets are like beads on a string with predictable distances between the planets. Some planet is going to be the "right distance" from the sun to get just the right amount of sunlight. If the sun is hotter, the planets further out will get the right amount, if the sun is cooler, the planets inward will get the right amount.
As far as the moon, the view that the moon was necessary for life to form (in tide pools) has fallen from favor.
As far as nutrients we get from the sun.. say what? What nutrients?

Not exactly like Earth no, but close enough to provide an identical environment? There are probably many thousands of similar planets in this very galaxy - and there are over 100 billion galaxies.
You say the Earth is just the right distance out but it may be that when stellar planetary systems form the rocky planets (venus, earth, mars) always form orbitals which make 1 or more suitable for our kind of life.
Besides thats another fallacy - assuming that for there to be other life the planets would have to be like us. Other life may like temperatures of 200 degrees and breathe sulfuric acid.

No, there can't be a hidden planet purely like Earth previous the solar, and there are 3 important the rationalization why: one million: Earth's orbit isn't a suited circle. it fairly is an elipse, and in accordance with Kepler's rules of planetary action, Earth's speed around the solar varies with the gap from the solar, rushing up whilst it fairly is nearer, slowing down whilst added away. meaning that any planet at the back of the solar would not stay hidden at the back of the solar in any respect situations, because it would in some situations peek out. 2: Gravity. If there have been an Earth-sized planet there its gravity might supply it away. You propose we'd purely think of it replaced into the different plents, yet that somewhat misses the element that we comprehend gravity slightly better than that. The planet Neptune replaced into discovered through its gravitational impact on earth Uranus. It replaced into the only planet to have been properly pointed out before all and sundry knew it replaced into there purely through its gravitational impact. Astronomers used Newton's calculations to perceive the place this planet must be, grew to become their maximum useful telescopes on that spot, and there it replaced into. 3: we've despatched many probes out into area that have taken pictures frmo positions properly removed from Earth, and no sign of any hidden planet exists.

One doco I watched stated that there are more stars in this universe than there is grains of sand on the planet. And if thats true then surely there would be a chance of there being a planet similar to our own some where out there. The problem we have at the moment is getting there.

The earth to some people is a rare planet and some scientists believe that life on earth is a freak accident and we are alone in the universe. Myself believes that there are to many possibilities
for there to be just us.

No, anymore than finding another person just like you are. But other planets that sustain oxygen sustaining life, yes. It just might take an awfully long time to find them.
Kind of a lonely feeling isn't it?

The odds of finding a planet exactly the same are a lot higher than finding one almost the same.

There are theories about parallel universes but it's still considered fiction. Check out this wiki page that talks about it:

Very. There are Billions and billions of galaxies and if there is no other life forms then that is a big waist of space.
