The Argument from Design
The universe could have been different from the way that it is in many ways. It could have had different laws of physics; it could have had a different arrangement of planets and stars; it could have begun with a more powerful or a weaker big bang.
The vast majority of these possible universes would not have allowed for the existence of life, so we are very fortunate indeed to have a universe that does. On an atheistic world-view, there is no way to explain this good fortune; the atheist must put this down to chance. On the view that God exists, though, we can explain why the universe is the way that it is; it is because God created the universe with beings like us in mind. This argument, strongly suggests the existence of a Creator(all knowing designer) that takes an interest in humanity.
The Moral Argument
Moral laws have the form of commands; they tell us what to do. Commands can’t exist without a commander though, so who is it that commands us to behave morally?
Why is there good and evil as these are abstract terms? Relative, subjective morality cannot be lived out.
Spiritual Nature.
Why does man have a worship nature ?
Can I recommend the
Daylight Atheism website to your attention? I have rarely found an apologist's argument that wasn't answered in full there.

"The cosmological version of the fine-tuning argument is more sophisticated, but nevertheless is not difficult to defeat. The key is to recognize that every step of this argument relies on implicit assumptions, none of which are supported by any evidence at all, and without any of which the argument collapses.
For example: how do advocates of this argument know how many different sets of values for the physical constants could have led to life? Perhaps life
as we know it would not exist if these values were different, but that does not prove that life
of any form could not exist. It could be that
most of the universes that would result from changing these constants would contain some sort of complex life, even if that life would in most cases be extremely different from what we are used to. Advocates of the fine-tuning argument implicitly assume that only one, or at most a few, sets of values could have led to conscious life of any form, but there is no possible way they can know this.
Furthermore, how do advocates of this argument know that all possible values for these constants were equally likely, or even that they could have been different at all? Defenders of the fine-tuning argument implicitly assume that the current values were selected uniformly at random from an infinite or at least a very large range of possibilities, but there is no possible way they can know this. Indeed, for at least a limited subset of cases, we know that this is
not true. Some physical constants are interrelated, such that a change to one would necessarily produce a change in the others. (For example, according to this
Talk.Origins Post of the Month, the permittivity of free space, the permeability of free space, and the vacuum speed of light are related in such a way.) It is very likely that as physics advances, this process of unification will continue, and we will discover even more and deeper interrelations. A complete unified theory, the dream of physicists, might well show that things are this way because they could not possibly have been different.
Finally, how do advocates of this argument know that there was only one chance to get it right? On what grounds do they assume that the universe we can observe constitutes the totality of existence? Multiverse theories, which posit an enormous or even infinite number of parallel universes of which one is our own, are a common feature of theoretical astrophysics. Naturally, if there are thousands or millions of universes each with a slightly different set of values for the physical constants, it should be no surprise that we find ourselves in a universe where the values are conducive to our existence, rather than one where they are not. This is very similar to the rebuttal to the planetary fine-tuning argument discussed above.
As we have seen, there is no good reason to suspect the universe was fine-tuned. But consider this: even if there
was fine-tuning, how do we know it was for
humans’ sake? Human beings have a long history of considering themselves the centerpiece of creation, and an equally long history of being proven wrong on that point. On what grounds do we assume that we are the pinnacle of existence, or even that our existence was intentional? Perhaps the creator simply thought stars were beautiful and wanted a universe full of them, and hasn’t yet noticed that interesting things have begun to happen on some of the little bits of ash circling them. Or perhaps the creator did desire life to come into being but is not interested in
human life. The evolutionary biologist J.B.S. Haldane, when asked what we could deduce about the personality of the creator by studying the creation, is said to have replied, “An inordinate fondness for beetles.”
The moral argument:
"A slightly different version of the moral argument, advanced by theists such as C.S. Lewis, states that there is a universal moral law, a standard of right and wrong which all human beings are innately aware of, even if some choose to violate it. The argument’s backers claim that such a moral awareness could only have been put into us by God.
The most significant problem with this argument is that human beings are
not all aware of the same moral law, as even a cursory examination of human history would reveal. In various societies throughout history, behaviors such as polygamy, segregation, slavery and racism, physical abuse as a method of discipline, infanticide, incest, pedophilia, human sacrifice, ritual suicide, ritual murder, cannibalism, genital mutilation and genocide were widely accepted, even encouraged. None of the societies that did these things seemed to feel that there was anything wrong with them; many justified their actions by appealing to their god. Some societies have shunned violence of any kind, while others have encouraged war and militarism. Some have advocated free speech and individual rights, while others have mandated conformity and the superiority of the state. Even today, there are furious debates over the ethics of topics such as gay marriage, abortion, capital punishment, sex education, drug legalization, contraceptive use and euthanasia, to name just a few. Claiming that God is responsible for humanity’s universal sense of right and wrong fails to explain why there is and has always been such widespread disagreement over morality.
On the other hand, atheism can accommodate both the existence of a moral law and the manifest fact that not every culture or individual is aware of it. The explanation is straightforward: morality is not something implanted in every person’s heart by a creator, but something derived from careful deliberation and a rational understanding of our place in the world and our relationships to each other. There is no reason why we should expect it to be immediately obvious to everyone, just as there is no reason why we should expect the laws of physics to be immediately obvious to everyone."
And finally, "Why does man have a worship nature". Well, who cares? Do you imagine that Apollo, or Odin, or Vishnu, or any of the non-Christian gods that people believed in and believe in actually exist, just because of their worshippers' belief? So why is the fact that many people are predisposed to be religious proof that they are correct?
I imagine that an evolutionary scientist would postulate that this is just an unintended side-effect of other features of our thinking. People are hard-wired to look for patterns. It serves them well when identifying a stalking predator creeping up on them, but poorly when they see a lightning bolt and imagine an invisible giant in the sky threw it, or that it must have been designed by some sort of celestial watchmaker.
In short: you can't get out of providing evidence. If you think God exists, give a good reason for it.
