As far as I know, there was no report of "life" popping up in a lab or in nature so far.
Everything that we know is only some copy with similarity to previous life-forms.
We certainly can mix some amino acids and stuff, and even some of the chemicals can retain some structure for a certain time and even form some proto-RNA-like structure (not sure how they called it in one document I have seen), but it's very very far from a living organism.
Does it mean that life cannot be "sparked" in today's Earth like conditions or, was it not even sparked here to begin with? I have read, as many others have done, this article: New research supports an idea that the Red Planet was a better place to kick-start biology billions of years ago than the early Earth was. They argue that you need molybdenum to create life-like structures and that it's not common in the right form on Earth.
What do you as biologists think about the statement that life cannot evolve on Earth because the conditions in the beginning of the Earth were not good for life to develop.
