If all of life(animals,plants) were to suddenly disapear on earth...?

i would have to agree with Average Joe. life on earth as we know it is a result of a series of chance encounters and evolutionary process. if we were to start again from a simple chemical "soup", all of the factors that were present before would have to be present again... since those factors were all contributed by chance it is unlikely that the same environmental factors will be present. another point to consider is the evolutionary process which relies on environmental factors... if the environmental factors are not the same second time round, it would lead to a completely different evolutionary pathway. who knows what forms of life would be!!!???
