from the beggining of bigbang that the universe was already expand(acc.to bigbang theory) about millions of years ago and i realize that the distance of one galaxy to the other is also expanded every seconds million times x million of years ago and it is faster than the speed of light.Why can evoltionist say that they saw other galaxy.we supposed to be very very very very far time million of years ago. from marl26gil@yahoo.com

1. Closer galaxies move away slower than further galaxies. For every 3 million light years, the seed the move away is increased by 70 kilometers per second. The speed of light is 300,000 kilometers per second. Now figure out how far away a galaxy has to be to be moving at half the speed of light.
2. The universe is Billions (13.7 billion to be exact) of years old, not just Millions. The earth is about a third as old: 4.5 billion years old.
3. Evolution is a biological theory, not a theory of cosmology. I'd suggest not listening to those who have been lying to you about what the science actually says and read some science for yourself.
4. It is possible to see one other galaxy without even a telscope (the Andromeda spiral). If you use a modest, but good, telescope, you can see dozens of nearby galaxies.

As was said, the facts remain as they are. They can be seen and they are not moving quite as fast as you think, though they are moving at a good speed. Even at that, we are seeing their light after that light has traveled for an extremely long time/ distance to get here. In the local group, which includes our Milky Way, light from M31 or Andromeda took two and a half million years to get here and M33 Triangulum galaxy about three million years. And those are the closest, with an uncountable number of galaxies out there. Abell 1835 is more than 13 billion year light travel but may have been more like 30 billion as it was spotted only by gravitational lensing and not reproved.

Space expands at the speed of light but not the matter in it.
There are many galaxies out to about 6 billion light years in radius,galaxies that we can see to-day.
Beyond that distance the earlier galaxies have gone out of existence.
The universe may be about 6 billion light years in radius but it could be much older than 6 billion years.

1: Expansion is not currently faster than the speed of light, therefore we can see distant galaxies.
2: We can say we see other galaxies in space because we DO see other galaxies in space. If you look using your own eyes and a telescope you will see them for yourself.

Considering how incoherent your question was, I should get the points just for answering.
We see the light of past days when we look at other galaxies. They are "visible" only in terms of the past but as time continues we can follow progression of the galaxies as they evolve.

1. Please redirect all creationist trolling to "Religion & Spirituality".
2. Please acquaint yourself with the Big Bang theory further so you come to understand what it actually predicts.
3. Simply put: No galaxies during inflationary phase, just energy. Inflationary phase ends. Decoupling. Visible galaxies form well within the visible universe. Visible galaxies might cross visibility horizon due to metric expansion eventually, but don't hold your breath to witness it.
