Why is it beneficial to use a theme when creating a presentation?

Using a theme in a presentation provides visual consistency, making it easier for the audience to follow along and understand the content. It enhances professionalism and can reinforce the message by aligning visuals with the topic. A cohesive theme also helps to engage the audience and maintain their attention, making the overall presentation more memorable. Additionally, it saves time in design, allowing the presenter to focus on content rather than formatting.
