dear friend.
man does have a creater and that is the logic side of it. i'll ask you this: is it logical to say that a house built itself or that it had a creator who designed it and fashioned it and created it (for example man).
With all due respect, your logic and analogy reflect an inadequate understanding of basic scientific knowledge. The evolution of life is readily identifiable within the principles of organic chemistry and physics. While the construction of a house relies heavily on physics, it relies very little on organic chemistry. As a matter of fact, I would go as far as to say, that the only organic chemistry to be found in the construction of a house, is that of the humans constructing it. Your logic that man has a creator, based on the correlation in your analogy, is tragically flawed.
the sense of life is to know that we were created by god, to acknowledge his power, to worship him and to please him because in this life we will only pass by, and by pleasing god we will have an aim in our short life, to be rewarded with heaven, wich in the end leads to sense, for example: life made sense to me while on earth because i was able to understand the existence of god which has brought me to eternal happines.
If that makes sense for you, fantastic! However, it is quite transparent in it's disregard for the knowledge that man-kind has accumulated to this point in time. It makes far more sense that man-kind is a product of many things that we have verifiable, observable and tangible knowledge of, rather than of an assumed creator that ins't supported by any verifiable evidence.
how simple is that
