Zohaib,
Bacteria came from the mix of different chemicals available at that time and the environment was just suitable for it.
The Earth is located in a zone known as the "Goldilocks Zone". this is the distance from sun in which life is feasible. there are other planets that coudl be in such Goldilocks zones from their respective stars. they could also have life.
the reason i told you about is that the Earth is located in a zone which is good for life.
there have been several experiments to understand how life formed, or how the basic constituents ( i.e Amino Acids) formed. some day humas might be able to replicate the genesis of simple life in laboratory.

Evolution has not stopped at human beings present form. but the thing is that evolution in complex organisms is too slow as compared with simple organisms. evolution does not take decdes or centuries: it take aeons or millions of years. that is the reason that you do not know about the process going on. our lives are too short to see it.
Evolution never said men were apes. such statements are based on complete ignorance of the theory of evolution. next time you want to criticize something, try to read it first. and it better not be from the website or book of an opponent.
"survival of the fittest" is not something that is understood properly. survival of the fittest does not mean that the species necesarily has to have strong muscles to survive. it just means that the species can adopt to the environment. and is able to pass on its genes to its next generation. that is what survival means in darwinism. if the species is able to live for hundred years but is not able to pass on its genes ( i.e it does not reproduce) then it will not be considered to have survived.
One more thing. evolution does not cater to your personal choices or wants.
try to educate yourself before you criticize.
