the big bang theory by edwin hubble can also be true. as there are no specific records that the universe has not changed and galaxies and their stars have not even moved a bit. since billions of years[13.7] due to the big bang our galaxy was created and now these galaxies are moving away.they had a big bang due to their gravitational attraction and so they are now receding away at infinite distances.

I am loosing interest in big bang theory. May be quasi steady state may be the solution. I start doubting the expansion when some here asked a question about the galaxies colliding with other galaxies. There are evidence to support that. Also the expansion is explained by the following way. All the galaxies and stars are on a balloon surface. And if the balloon is blown it will expand carrying all the galaxies away from each other. If this analogy is true then galaxies can not collide with each other.
Evidence of Colliding galaxies is more believable than the expansion. The red shift is the only measurement that is interpreted as the expansion. One has to revisit and see what is the real cause of this red shift. That will show the expansion is not happening and hence big bang theory will go away.
Apart from the expansion the other explanations are very hard to believe. Even harder than believing GODs creation. So to do some justice to the evolution theory scientists should come up with some believable explanation of how the universe came in to existance

They are two different theories. The Steady State theory has been superseded by the Big Bang as the most accepted theory. They are both still, however, theories and scientists are still working on the best explanation from several theories. A new mystery they are incorporating into the mix is the fact that the expansion of the universe is accelerating, which was unexpected...

Steady-State Theory = Wrong
"Problems with the steady-state theory began to emerge in the late 1960s, when observations apparently supported the idea that the universe was in fact changing: quasars and radio galaxies were found only at large distances (i.e., redshift, and thus, because of the finiteness of the speed of light, in the past) not in closer galaxies. Halton Arp, also since the 1960s, has been taking a different view of the data, claiming that evidence can also point to quasars existing as close as the local Virgo cluster, however, this theory is not accepted by mainstream scientists today.
For most cosmologists, the refutation of the steady-state theory came with the discovery of the cosmic background radiation in 1965, which was predicted by the big bang theory. Stephen Hawking said that the fact that microwave radiation had been found, and that it was thought to be left over from the big bang, was "the final nail in the coffin of the steady-state theory." Within the steady state theory this background radiation is the result of light from ancient stars which has been scattered by galactic dust. However, this explanation has been unconvincing to most cosmologists as the cosmic microwave background is very smooth, making it difficult to explain how it arose from point sources, and the microwave background shows no evidence of features such as polarization which are normally associated with scattering. Furthermore, its spectrum is so close to that of an ideal black body that it could hardly be formed by the superposition of contributions from dust clumps at different temperatures as well as at different redshifts. Steven Weinberg wrote in 1972,
The steady state model does not appear to agree with the observed dL versus z relation or with source counts ... In a sense, the disagreement is a credit to the model; alone among all cosmologies, the steady state model makes such definite predictions that it can be disproved even with the limited observational evidence at our disposal. The steady-state model is so attractive that many of its adherents still retain hope that the evidence against it will disappear as observations improve. However, if the cosmic microwave background radiation ... is really black-body radiation, it will be difficult to doubt that the universe has evolved from a hotter, denser early stage.
As of 2006, the majority of astronomers consider the big bang theory to be the best description of the origin of the universe. In most astrophysical publications, the big bang is implicitly accepted and is used as the basis of more complete theories. At the same time, after the unexpected observation of an accelerating universe in the late-1990s, there were efforts to develop quasi-steady state theories, in which it is said that there is not a single big bang but rather multiple big bangs over time which create matter."

All observation indicates that the universe is consistent with the Big Bang Theory.
Infinite density is not a part of the Big Bang Theory. Density only applies to mass objects. At the time of the Big Bang there was no mass. The mass in the universe came about as the universe cooled. The early universe was only energy. It is not know the form of the energy at the very start but it is know that at the time when mass particles were able to form there was also radiation. The radiation that was not hot enough to form particles was left over and is today seen as the Cosmic Microwave Background Radiation.
The energy of the universe is not infinite. All the energy in the universe is fixed and unchanging. Part of the effort today is to try and determine the size and mass (energy) of the universe.
All objects and energy of the universe is moving outward from the Big Bang. Observation indicates that outward transition from the Big Bang is not a spatial transition. The observation that all objects are moving away form us could only result from all objects moving on a line that is perpendicular to all spatial directions. Objects that move perpendicular to each other are said to be moving in different dimensions.
You can draw an example on a piece of paper. Mark a point in the center of the paper. From that point draw radial lines outward in different directions. At any given distance from the center point you will notice that the lines keep increasing their distance from each other. The distance between the lines is on dimension and the lines drawn outward from the center point in a different dimension. The distance between the lines represents the spatial dimension.
There are too many indicators for the Big Bang to go through them all here. Look them up on the Internet.

Quasi-Steady State theory arose in the early 1990's which suggests there has been numerous mini-bangs which seems to me to be the most preferrable. Steady State theory is much older, since the early 20th Century but the existence of microwave radiation is difficult to dispute.

I believe in the "Big Bang" theory because of the mounting evidence like the expansion of the universe and the primordial echo from the expansion.

it has been found out by edwin hubble that all the galaxies are moving away from one another which proves that universe is expanding. this proves that there must be some initial explosion that triggered it to expand whis goes on to prove that universe had started from an explosion.
and you are talking about infinite density? what do you say about black holes?eh?

Live is a mystery to be lived and not a problem to be solved. If you can take the building blocks of a cake and blow them up and get a cake then I will agree with Big Bang. Other than that I believe in intelligent design. I did not say creationism mind you, but that the universe was designed intelligently if you want to call that person god that's up to you.

Basically, God said Bang, and the earth was created. Or it could have been the Great Spirit. There are so many things that mere mortal cannot know. We havent' evolved that much yet.
